Stability Test Results

New Packaging
and Shipping

Environmental commitment

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:

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