RayBiotech offers a diverse selection of over 18,000 monoclonal and polyclonal primary antibodies. RayBiotech's primary antibodies were developed to target multiple different proteins relevant to cell biology, neurobiology, immunology, virology, and many other fields. We have also developed secondary antibodies that target multiple host species immunoglobulin isotypes. These are available unlabeled or pre-conjugated to many different reporter systems including alkaline phosphatase, biotin, FITC and other labels.
