Polyclonal Antibody Production in Rabbits

We use New Zealand white rabbits for the production of your polyclonal rabbit antibodies. It is the most used species to produce custom polyclonal antibodies and antisera. The advantages are a good amount of high-titer and high-affinity antibodies from the atisera at low costs. In addition rabbits are easy to handle and additional serum collections are easy to prepare and cost efficient. The final amount of antiserum is very good comparing with mice, rats or guinea pigs. Davids offers every step from the antigen synthesis/preparation to your final antibody. We help you with the decision, which kind of antigen is most suitable for your project and what kind of purification you need.

Antigen Requirements

For the production of polyclonal rabbit antibodies a wide range of antigens can be used (Table 1).
When the purified (native) protein is available, it is usually the first choice for the antibody production. Purified proteins can be send at -20°C or -80°C to Davids wih cool packs or dry ice. We start the immunizations as soon as your antigen arrives. For proteins that are hard to purify, you can use our SDS-gel extraction service. In this case you load your protein to multiple bands of a SDS-gel and cut your specific gel bands from the gel. Send the gel pieces at room temperature to Davids. When the expression plasmid is available and time or equipment is not available for the expression and purification, you can use our protein expression service in E. coli.
For hard to express proteins, or proteins you only know the sequence from, we recommend to synthesize peptides that represent your protein. These peptides are conjugated to a carrier like KLH or BSA to improve the antigenicity prior to the immunization process.
The immunization of whole cells (bacteria, fungi, other eukaryotic cells) require a preparation to improve the presentation of the cells to the immune system. Please use Davids Cell Preparation KIT to improve the presentation of the surface from cells to the immune system. DNA as antigen is prepared by liposome introduction or by cationic detergents. Small molecules like drugs, toxins or haptens need to be prepared for immunization individually. Though if you have another antigen or when your antigen doesn't fit the requirements in the Table 1, you can contact us: info@davids-bio.com.

Immunization Schedules

Comparison of titer development after immunization Each antigen profits for an optimized immunization schedule. With Davids established immunization schedules you profit from our experience. In addition to our well established immunization schedules we are able to follow your individual one.
Our 63-day Protocol includes 5 immunizations. After the third one (day 35) we take a test bleed and perform an ELISA titer determination. You are able to receive an aliquot of the test bleed and the results of the ELISA titer determination. After day 63 you receive the antiserum or we continue with a purification of the antiserum. The 63-day program is best for unknown antigens to achieve highest titers in a good time.

Davids 28-day SuperFast Immunization Protocol uses superior adjuvants and an optimized immunization schedule. The titers and antisera are comparable with our 63-day program (see picture). For peptides and small molecules Davids recommends the 63-day program.

Davids starts the immunizations as soon as the antigen arrives, usually at the same day. Table 2 shows an overview of our most popular polyclonal rabbit antibody services.

Rabbit Antiserum Purification

Davids superior purification services for your polyclonal rabbit antibodies lead to high quality and pure antibodies. Most common is the affinity purification, which we recommend for many applications like WesternBlot or IHC, to achieve specific antibodies that only recognize your antigen. This service is available for Proteins, Peptides and other antigens.
In addition we offer ProteinA purifications to receive a pure IgG fraction or depletions to get rid of unwanted antibodies that i. e. recognize tags, amino acid modifications or E. coli proteins.

Additional Services

To determine if a preimmune reaction exists before immunization Davids offers to determine in ELISA, which rabbit has the lowest reaction with your antigen. This can be important, when you want to minimize a cross-reactivity. Here we are able to immunize a rabbit that show only a small immune reaction to your antigen. Within the immunization schedule Davids can take additional small (0.5 ml) or large bleeds (15 ml) for ELISA determinations or for your applications.
