Where can I find the concentration of my antibody?

For a recently purchased antibody, the concentration will be found either printed directly on the vial label or in the Certificate of Analysis (CoA). CoAs for the current shipping lot of many of our products are available on the right-hand side of the product webpage next to the data images.

For the concentration of a previous antibody lot, please contact CST technical support by submitting a form online or emailing us at [email protected].
