DONKEY ANTIBODIES
Most commercially-available secondary antibodies are polyclonal, being purified directly from the serum of animals that had been immunized with a particular antibody species, subclass and fragment type. The specificity of a secondary antibody depends on the antibody sample that is injected as the immunogen and on the type of purification used to prepare the final product. BioFX offers secondary antibodies to nine different animal species (including mouse, human, rat, hamster, rabbit, goat, sheep, donkey and chicken) and to several antibody subclasses.  They are available in a variety of conjugate forms and specific to the most common species requested by researchers.
