Normal Sera are non-immune serum samples that contain the usual complement of serum proteins, including the various classes of immunoglobulins. Normal serum provides a sufficient quantity of endogenous proteins to saturate and block nonspecific binding sites on fixed samples or assay substrates. When used as an antibody diluent, the non-immune serum also supplies a native chemical environment for antibodies to function properly without adding foreign protein components.

LSP offers sera from a range of species including Bovine, Chicken, Goat, Guinea pig, Horse, Pig, Rabbit and Sheep.
