Polyclonal Antibodies

Polyclonal antibodies are antibodies that are secreted by different B cell lineages within the host (whereas monoclonal antibodies come from a single cell lineage). They are a collection of immunoglobulin molecules that react against a specific antigen, each identifying a different epitope. Choose between properties like host, clone and antigen to get the antibody you need. Our staff supports you finding the right product via phone, live chat or email.

If you want to use an unconjugated primary, don't forget the corresponding secondary antibody!
