Polyclonal antibodies (PAbs) are heterogeneous mixtures of immunoglobulins that recognize multiple distinct epitopes on a single antigen. This multi-epitope binding provides greater tolerance to minor structural variations in the antigen, making polyclonal antibodies particularly well suited for neutralization applications, where broad epitope coverage improves the likelihood of effective target neutralization.
PBL Assay Science offers a comprehensive portfolio of polyclonal antibodies validated for use across a range of applications, including ELISA, neutralization assays, western blotting, flow cytometry, immunoprecipitation, and immunohistochemistry. Every individual lot is tested for interferon (IFN) neutralization activity, ensuring consistent potency and reliable performance from lot to lot.
