Polyclonal Antibody Development are critical reagents used in many applications in research and diagnostics, including immunohistochemistry, Western blot, ELISA, flow cytometry, and more. Historically, polyclonal antibodies have played a prominent role in immunoassay development and remain an important tool for detection in conjunction with monoclonal antibodies to improve specificity and performance. Due to their natural heterogeneity and multi-epitope recognition, polyclonal antibodies are highly sensitive and offer broad-spectrum efficacy for detecting a variety of target epitopes. However, their inherent lot-to-lot variability can make it difficult to ensure consistent experimental results and should be considered when using these reagents in immunoassays.

The production of polyclonal antibodies involves immunizing an animal with the target antigen, which then responds by producing diverse antibody responses against multiple epitopes on the target protein. These antibodies are then enriched through affinity purification, which captures antibodies with a high degree of binding to the target antigen. Despite the limitations of lot-to-lot variability, polyclonal antibodies remain a popular choice for many researchers and diagnostic laboratories.
