Product Shelf-Life

The table below lists shelf-life expectations for Cell Signaling Technology (CST) products. CST products can be expected to perform at optimal levels during the shelf-life period when stored under the recommended conditions. Reference dates are printed on CST product vials and exterior product packaging. These dates indicate the date (month and year) that a product vial was filled and packaged, respectively. Vial filling and packaging dates are not always the same. For single component products such as individual antibodies, the starting point for the expected shelf-life is indicated by the reference date printed on the vial label. For multi-component kit products the reference date printed on the barcoded kit box label indicates the starting point for the expected shelf-life.
