Complete portfolio of custom services

Customized production schedule to optimize production schedule

Extensive experience with a diverse set of antigens

Polyclonal antibodies are a mixture of antibodies directed against multiple epitopes of an antigen. These polyclonal antibodies can recognize the corresponding protein by interacting at various regions, allowing researchers to detect, quantify and characterize the antigen. The major benefit of using a polyclonal antibody preparation is the ability to recognize full-length, truncated or otherwise modified antigens in various matrices.

We offer a complete portfolio of custom polyclonal antibody services against a variety of antigens, including peptide synthesis, immunization campaigns in various host species, purification, labeling and characterization. Producing polyclonal antibodies involves three phases: immunization, monitoring of the immune response and antibody purification. Each step is customizable, and we’ll work with you to create an optimized production schedule to maximize serum volumes and antibody titers.

Considerations for a successful polyclonal antibody production
