Our water-soluble QuickAntibody series of immunological adjuvants are divided into four types: 5-week immunological adjuvant for mice, 3-week immunological adjuvant for mice, 2-week immunological adjuvant for mice, and 8-week immunological adjuvant for rabbits. The 5-week adjuvant for mice has the best antibody affinity and antibody titer. Therefore, when preparing monoclonal antibodies, we generally recommend using the 5-week adjuvant for mouse immunization. For the preparation of polyclonal antibodies in mice, we generally recommend using a 3-week immunological adjuvant for mice. If time is tight or the quality requirements for antibodies are not high, mouse monoclonal antibodies can be prepared using 3-week mouse immunological adjuvants, and mouse polyclonal antibodies can be prepared using 2-week mouse immunological adjuvants.

Compared with the conventionally used Frejens adjuvant, QuickAntibody immunoadjuvant has multiple advantages such as a short immune cycle, fewer injections, no need for emulsification, low antigen dosage, high antibody titer, high antibody affinity, and easy acquisition of conformational epitope antibodies. The details are as follows: QuickAntibody only requires two doses of immunization, whether for the preparation of monoclonal or polyclonal antibodies, and can reduce the number of immunization doses compared with Frejner's adjuvant. 2.QuickAntibody can significantly reduce the total amount of antigen used by decreasing the number of immunization doses and the amount of antigen per dose. The recommended dosage of the antigen is as follows: (1) For subunit protein antigens with relatively weak immunogenicity, the dosage is 5-50 per dose. g (usually 5-20 μ g for mice and 20-50 μ g for rabbits); (2) Inactivated whole virus or whole bacteria and virus-like particle antigens with strong immunogenicity, 1-10 μ m per injection; g (usually 1-5 g for mice and 5-10 g for rabbits). 3.QuickAntibody features rapid antibody production, high antibody titer and strong antibody affinity. Take the standard immunization program as an example. Whether it is for the preparation of monoclonal or polyclonal antibodies, only two doses of immunization are needed within three weeks. Usually, a high affinity antibody level with an ELISA titer (Cutoff value of 0.1000) as high as 1:10,000-1:10,000,000 can be obtained by the fifth week. 4.QuickAntibody does not disrupt the natural conformation of the antigen, thus making it easy to screen and obtain monoclonal antibodies targeting conformational antigenic epitopes. This is an important feature that Frexner's adjuvant does not possess. 5.QuickAntibody is a water-soluble adjuvant. When in use, it does not require the complex emulsification process of Freund's adjuvant. The antigen and adjuvant only need to be simply mixed to immunize animals. 6.QuickAntibody uses the muscle immune pathway, which greatly facilitates its application compared with the conventional mouse monoclonal antibody preparation process that uses foot pads or endospleen immunity. One important use of QuickAntibody is that it can be conveniently used to prepare polyclonal antibodies for mice. Conventional polyclonal antibody preparation mostly uses rabbits. Not only are there many immunization shots, large amounts of antigen used and slow antibody production, but also due to the high technical requirements, it is often necessary to entrust specialized units to prepare them. With the QuickAntibody adjuvant, any laboratory animal personnel can conveniently and quickly prepare mouse polyclonal antibodies. The standard immunization program only requires simply immunizing 5 mice, and 1ml of high-quality mouse polyclonal antibodies can be obtained after five weeks. It is strongly recommended to use this adjuvant to prepare mouse polyclonal antibodies. 1ml of high-quality mouse polyclonal antibodies is sufficient to meet the experimental needs of the vast majority of users, including for enzyme-linked immunosorbent assay (ELISA), Western blotting, flow cytometry, immunohistochemistry and immunoprecipitation, etc.

No need.

So far, QuickAntibody has been used to immunize various species such as mice, rats, rabbits, guinea pigs, goats, alpacas, chickens, and monkeys, and the results have all been good. The adjuvant itself is a mixture of multiple adjuvants rather than a single adjuvant. Species Adjuvant Type Antigen dosage ug Antigen Volume ul Adjuvant Volume ul Mouse QuickAntibody-Mouse 5-40ug 50 50 Rat, Guinea Pig QuickAntibody-Mouse 20-50ug 70 70 Rabbit, Chicken QuickAntibody-Rabbit 50-100ug 100 100 Goat, alpaca QuickAntibody-Rabbit 200-500ug 300-500 300-500 Monkey QuickAntibody-Rabbit 200ug 200-300 200-300

The amount of adjuvant used for each immunization is 50 μ l, and there are two immunizations in total. Therefore, 1ml can immunize approximately 8 mice. Standard procedure: One mouse is immunized with two injections, 50 μ l of adjuvant and 50 μ l of antigen, totaling 100 μ l for one injection. Therefore, the adjuvant dosage for one mouse is 100 μ l. Each 1ml tube of our adjuvant can theoretically immunize 10 animals, but due to the damage of the syringe used and the adhesion of the centrifuge tube, etc., it has been affected. Only about 8 mice can be immunized.

Mix and use immediately. Take it to the animal room and mix it evenly. Immunize it into the animal's body within 10 minutes after mixing. If left for a long time, the precipitate will slowly sink, and the distribution of effective components will be uneven, which will affect the immunization effect. Customers can also premix in the laboratory first. After entering the animal room, they can directly mix by pipette tip or shake up and down to mix. Do not use a syringe to mix by pipette, as it will not mix well. How to immunize: With the special QuickAntibody water adjuvant of Boao Long, the site for immunizing mice is the inner muscle of the hind leg root. It is a single-point injection immunization. The leg muscles of mice are not too many, so the needle should not be inserted too deeply to avoid piercing the bone. Shock immunoassay: Intraperitoneal injection of 20 to 50 micrograms of antigen, with a volume of 100 to 200 micrograms. The intraperitoneal injection site was located in the lower abdomen on the left or right side of the mouse, avoiding the liver and the lower and middle abdominal bladder, and penetrated the peritoneum along the Angle of the leg. When the 1ml syringe needle enters about one-third, there is a feeling of being pierced through. "

Some of our adjuvants are used as adjuvants for human vaccines later on. All optimizations are carried out using muscle immunization. Therefore, it is recommended to use muscle immunization, but subcutaneous one-point or two-point immunization can also be used. Intraperitoneal immunization and tail vein immunization are not recommended.

Our adjuvant is for mouse hind leg muscle immunization. Due to some clients' previous use of intraperitoneal immunization or subcutaneous multi-point immunization, they are not familiar with muscle immunization and may experience bulges. The main reason for the bulges is that the injection has reached the subcutaneous layer. Clients can apply it deeper. For the first use, it is recommended to wipe the hind leg with an alcohol cotton swab. During immunization, avoid the two veins on the inner side of the hind leg. After immunization, rotate the needle half a circle, let it stand for a few seconds, and then pull it out.

It is generally not recommended to shorten the time as it involves the affinity and titer of antibodies. However, for the measurement of serum titer, our instructions state that it should be done 14 days after the second immunization. In terms of time, the titer can be measured 7 to 10 days after the second immunization. Once the titer reaches the standard, several impulse immunological tests can be combined

Plasmids won't work, but proteins and viruses can

Our adjuvants have been tested through tens of thousands of antigen immunization experiments. Currently, the types of antigens available for immunization include cells, viruses, proteins, polypeptides, polysaccharides, lipids, heavy metals, antibiotics, pesticides, drugs, and food safety compounds, all of which have achieved excellent results. We have a wealth of industrial customer cases and hundreds of literature articles to support this.

For nucleic acid immunization, our adjuvant is not applicable. Liposomes can be used instead.

Some of our adjuvant components are used for vaccine research and development, but the cooperation will not be completed until the second half of 2022. Our adjuvant components are used for the development of human vaccine adjuvants. Generally, customers cannot afford to use them for animal vaccines, except for pets and special animals.

The precipitate is the effective component of our adjuvant and cannot be removed by centrifugation. Last year, there was less precipitate in the adjuvant, but this year there is more. The adjuvant was updated and replaced in November 2021. The new adjuvant has been verified for more than five years and has better effects.

This adjuvant is a confidential formula of our company. The specific ingredients are not available for disclosure. An English description of the principle can be provided QuickAntibody is a proprietary novel adjuvant designed specifically for the preparation of monoclonal as well as polyclonal antibodies in mice. It is formulated with PAMPs (pathogen associated molecular patterns) and cationic polymers to activate cytosolic PRRs (pathogen recognition receptors)."

For general antigens with weak immunogenicity or for customers using our product for the first time, the titer may not increase after two doses. At this point, a third dose can be administered 14 days after the second dose, which usually leads to an increase of an order of magnitude. However, the maximum number of doses is four. If the titer still does not increase after four doses, it is generally recommended to re-administer or modify the antigen. The more common ones are small molecule antigens such as polypeptides and small molecules. It is generally recommended to increase the number of aa peptides to more than 20, which can effectively enhance the antibody titer.

This is normal. Traditional adjuvants contain BCG vaccine. BCG vaccine is a strong immunogen. Many B cells in the spleen target BCG vaccine, so they are larger

The five-week adjuvant for mice was the first to come out. Based on the five-week adjuvant for mice, the three-week adjuvant and the two-week adjuvant were optimized. Their main components were the same, but the ratios were slightly different. Therefore, it is generally not recommended to mix them. There are significant differences in adjuvants between rabbits and mice Mouse adjuvants and rabbit adjuvants are not recommended to be mixed. One of the main components of adjuvants has species selectivity. Mouse adjuvants themselves can be mixed, but if there is enough time, it is not recommended to mix them.

Just looking at the price, it's a bit expensive, but it saves time cost Save one month's time cost and the cost of raising mice 2. Save the amount of antigen used, only 1/5 to 1/10 of the original. The price of 1mg of natural antigen can reach tens of thousands of yuan. Our adjuvant components are very stable. We have conducted a one-month test at 50℃ and found no effect. However, it cannot be frozen, as freezing can have a significant impact on the immune effect. For general storage, it can be placed once near the door of a 4℃ refrigerator, not at the innermost part. Some refrigerators have poor temperature control, and placing it at the innermost part will keep the temperature below 0℃. Sure. The functions of different adjuvants are similar, and different adjuvants can be tried to be used alternately

They can be used in combination. Any immune method can produce the effects of cellular immunity and humoral immunity.

The main function of impulse immunity is to activate spleen cells to a relatively high extent, which has a significant impact on the ability of hybridoma cells to secrete antibodies after fusion. Therefore, direct antigen impulse immunity is still recommended. Moreover, cells themselves as immunogens are likely to have the problem of low titer, and their components are rather diverse. The target epitope protein may not necessarily be the dominant immunogen. Previously, General Manager Yan said that taking on similar technical services for preparing antibodies through cellular immunity basically could not meet the experimental expectations.

Glycoprotein immunogens, such as CA125, are highly prone to generating IgM and difficult to obtain IgG

The surface of bacteria is all polysaccharides, making it difficult to obtain protein epitope antibodies. Polysaccharide epitope antibodies have a high titer. It can be attempted to immunize 1-5 micrograms after quantification by BCA

A: Previously, some customers tried to switch to our QuickAntibody. 5W adjuvant, administer two injections in a cycle as per the instructions. If you are really in a hurry, you can also try 30,000. The water adjuvant for two injections. However, the function of the immune system declines with age, so continuing immunization may increase the risk of inappropriate age for mice

Rabbit adjuvants and mouse adjuvants should not be mixed. They are species-specific and it is not recommended to use them together
