All CST packaging is made from the highest percentage of post-consumer waste available. The styrofoam cooler we previously shipped our products in has been replaced with an environmentally friendly cooler. The insulation material of this new cooler is made from 100% compostable rock and slag wool that is wrapped in a biodegradable film and placed in a box made from 70% post-consumer waste.

Additional Packaging Information.

As a new antibody is developed, Cell Signaling Technology (CST) scientists test the antibody’s stability and activity following a storage period of more than 7 days at -20°C, at room temperature and at 37°C. All antibodies tested have been found to be just as active and stable when stored at room temperature as on ice. If you have any questions, please email us at: info@cellsignal.com or call our Technical Support number: 877-678-8324 (877-678-TECH) to speak with one of CST’s staff scientists.


After receiving your order, please continue to store our antibodies in your -20°C freezer.

For all Tests:

  1. Antibody was stored at -20°C.
  2. Antibody was stored at room temperature for one week prior to use.
  3. Antibody was stored at 37°C for one week prior to use.
