Secondary Antibodies


Secondary Antibody product focus Q3

American Research products prides itself on supporting your whole research journey.  The success of many laboratory techniques depends not only on the primary antibody but also on the quality of the secondary antibody.  We have focused on building a wide variety of high quality secondary reagents to support your research across species, isotypes and subtypes.

The target antigen of a secondary antibody is another antibody.  If the antibody is raised against the antibody binding domain it is called an anti-idiotype antibody.  However, if the antibody is raised against the constant region of an antibody it is usually referred to as a secondary antibody.  For example, an antibody against Human IgG1 raised in goat would be a Goat anti-IgG1.
