The CST Antibody Performance Guarantee

As a company of scientists, we understand how important it is to work with antibodies that are specific and consistent from lot-to-lot. To ensure product performance, we validate all of our antibodies, in-house, in multiple research applications. If a product does not perform in your experiment as described on our website or datasheet, please contact your local CST office or nearest distributor (see below for contact information) within 12 months of product receipt. The same expert scientists who produced your antibody will guide you through a few simple troubleshooting steps, and if your issue is not resolved, we will replace the antibody at no cost to you, or provide you with a credit.
