Secondary Reagents

Secondary antibodies and related reagents are vital tools for immunological assays. We offer a range of high quality, affinity purified secondary antibodies that can be used in a variety of assays in conjunction with our range of primary antibodies.

Secondary reagents

The secondary reagents supplied by the Native Antigen Company include a range of highly purified goat polyclonal antibodies against human, mouse or sheep IgG. These antibodies are available unconjugated and are also available conjugated to widely used enzymes, horseradish peroxidase (HRP), alkaline phosphatase (AP) or to the popular fluorochrome fluorescein isothiocyanate (FITC). Additional secondary reagents include streptavidin conjugates, which are suitable for use in a wide range of applications to detect biotin-conjugated detection reagents. All the reagents supplied are suitable for immunoassay research and development.
