Polyclonal antibodies are typically produced by the inoculation of a suitable mammal, such as a mouse, rabbit, or goat. Larger mammals are often preferred as the amount of serum collected is greater. An antigen is injected into the mammal, typically over several weeks, inducing the B-lymphocytes to produce immunoglobulins (IgG) specific for the antigen. Polyclonal IgG is purified from the mammal’s serum. Our polyclonal antibodies are used in many applications including western blot, flow cytometry, ELISA, immunohistochemistry, and immunofluorescence.
