Normal Porcine Serum Control, 31890, from Invitrogen., 31890, from Invitrogen. Species Reactivity: Not Applicable; Applications: Blocking Assay, Control, Immunocytochemistry, Immunofluorescence, Immunohistochemistry.

nNormal Sera are non-immune serum samples from goat, human, mouse, rabbit and other species that contain the usual complement of serum proteins, including the various classes of immunoglobulins that exist in healthy animals of the particular species. Normal serum provides a sufficient quantity of endogenous proteins to saturate and block nonspecific binding sites on fixed samples or assay substrates, making it useful for immunodetection methods, especially those involving tissue samples such as immunohistochemistry (IHC). Normal sera are also useful as controls for testing general and specific antibody purification methods. When used as an antibody diluent, non-immune serum also supplies a native chemical environment for antibodies to function properly without adding foreign protein components.
