Rabbit Antibody Production

Antisera & Affinity Purified Antibodies

For the manufacturing of your polyclonal rabbit antibodies, we select New Zealand white rabbits. It is the most often chosen species for the production of custom polyclonal antibodies and antisera. The benefits include a large quantity of high-titer and high-affinity antibodies from antisera at a reasonable cost. Furthermore, rabbits are easy to handle, and subsequent serum samples are simple to prepare and cost effective. When compared to mice, rats, or guinea pigs, the ultimate amount of antiserum is very good. Davids provides every stage of the process, from antigen synthesis/preparation to your finalized antibody. We assist you in determining which antigen is most suited to your project and what type of purification is required.

Antigen Requirements

A variety of antigens can be used to generate polyclonal rabbit antibodies (Table 1). When accessible, pure (native) protein is generally the first choice for antibody production. Purified proteins can be sent to Davids at -20°C or -80°C using cold packs or dry ice. As soon as your antigen arrives, we begin with the vaccinations. You can utilize our SDS-gel extraction service for difficult-to-purify proteins. In this case, you load your protein onto various bands of an SDS-gel and then cut the specific gel bands from the gel. Send the gel pieces to Davids at room temperature.

When an expression plasmid is available but there is insufficient time or equipment for expression and purification, you can use our protein expression service in E. coli or use peptides that represent your protein. For proteins, that are difficult to express or proteins you only know the sequence from, we recommend to synthesize peptides that represent your protein. Prior to vaccination, these peptides are conjugated to a carrier such as KLH or BSA to increase antigenicity.

Immunization of complete cells (bacteria, fungus, and other eukaryotic cells) need a preparation to enhance the cells' presentation to the immune system. Please utilize Davids Cell Preparation KIT to increase cell surface presentation to the immune system. Liposomes or cationic detergents are used to prepare DNA as an antigen. Small compounds, like as drugs, toxins, or haptens, must be specially prepared for immunization. However, if you have another antigen or if your antigen does not meet the standards in Table 1, please contact us with our contact form: Antibody Creator. Click on the selected antigen in the table for further details.

Immunization Schedules

Comparison of titer development after immunization Each antigen profits from a well-planned vaccination program. You benefit from our experience when you use Davids established immunization schedules. We can follow your personalized immunization program in addition to our well-established ones. Five immunizations are included in our 63-day Protocol. After the third (day 35), we take a test bleed and determine the ELISA titer. You can obtain an aliquot of the test bleed along with the ELISA titer determination results. After day 63, you will either receive the antiserum or we will proceed with the antiserum purification. The 63-day strategy is ideal for unknown antigens in order to produce the greatest titers in the shortest amount of time.
Davids begins with the immunizations as soon as the antigen arrives in our lab, which is usually the same day. Table 2 lists our most popular polyclonal rabbit antibody services.

Rabbit Antiserum Purification

The exceptional purification services provided by Davids for your polyclonal rabbit antibodies result in high quality and pure antibodies. The most popular option is affinity purification, which we suggest for many applications such as WesternBlot or IHC to obtain specific antibodies that identify just your antigen. This service is available for proteins, peptides, and other antigens. In addition, we provide ProteinA purifications to get a pure IgG fraction, as well as depletions to remove undesired antibodies that detect tags, amino acid changes, or E. coli proteins.

Additional Services

To verify if a preimmune reaction occurs prior to vaccination, Davids recommends utilizing ELISA to discover which rabbit has the lowest reactivity with your antigen. This is helpful when trying to lower cross-reactivity. Here, we may immunize a rabbit that has just a minor immunological response to your antigen. Davids can collect extra small (0.5 ml) or big (15 ml) bleeds throughout the vaccination plan for ELISA determinations or for your applications.
