We are phasing out our shipments in Styrofoam coolers and will begin sending our products in boxes or envelopes made from recycled fiber containing a minimum of 50% post-consumer waste. This change in packaging conserves resources and energy and means that over 17,500 cubic feet of landfill space will be saved each year in the U.S.

As a new antibody is developed, 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: 1-877-687-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.
