Anti-human secondary antibodies enable detection and signal amplification of primary human immunoglobulins (Ig). Raised from a variety of host animals, these anti-human antibodies are intended to target human Ig isotypes, including IgA (IgA1, IgA2), IgD, IgE, IgG (IgG1, IgG2, IgG3, IgG4), and IgM. These secondary antibodies are generally conjugated to labels for detection, including HRP, alkaline phosphatase, biotin, and various fluorophores. Note that each antibody will have a unique immunogen and will bind to a specific epitope on the human immunoglobulin. The location of the epitope can vary by amino acid sequence and protein chain.
