How do I store the Biolaminin stock vial properly?

The Biolaminin stock solution has long-term stability when stored at -20°C to -80°C. Please refer to the product-specific CoA. Repeated freeze/thaw should be avoided. For your convenience, you can aliquot the Biolaminin stock solution to smaller aliquots and store at -80°C. 

Thawed Biolaminin stock is stable for at least 3 months when stored at +2°C to +8°C under aseptic conditions. Avoid long exposure of the protein to ambient temperatures. Laminin coated plates are recommended to be used as fresh as possible but, for your convenience, coated plates and diluted coating solution can be kept at 2-8°C for up to 4 weeks. Seal the plates (e.g. with Parafilm®) to prevent evaporation. The Biolaminin matrix will be inactivated if let dry.
