Stability Test Results

As a new antibody is developed, Cell Signaling Technology (CST) scientists will typically test the antibody’s stability and activity by western blot after storing samples of the antibody, separately and simultaneously, for a period of 7 days at -20°C, at room temperature, and at 37°C. Antibodies that passed stability testing have been found to be just as active and stable after 7 days of storage at 37°C and 7 days at room temperature as compared to storage at -20°C. To learn more about our stability testing and how you can expect to receive your products from CST, read our blog post on the topic. If you have any further questions, please contact our Technical Support team.

After receiving your order, please continue to store CST antibodies® as indicated on the product sheet.

For all Tests:

  • A: Antibody was stored at -20°C
  • B: Antibody was stored at room temperature for one week prior to use.
  • C: Antibody was stored at 37°C for one week prior to use.
