The recommended temperature range for products stored at -20°C is -15 to -25°C. However, this product ships globally at ambient temperatures, year-round. While stability studies at -10°C have not been performed, short excursions outside of the recommended range are not expected to be detrimental to the product quality.

What is the stability of this material after Lyophilization? Can I save it in the -20^0C?
1 answer-
This product is provided as a lyophilized powder. When stored appropriately at -20ºC, the material is quite stable and not assigned an expiration or retest date. A warranty period of one year from the date of shipment applies. Following reconstitution, stock solutions remain active for one week at 2 – 8ºC. Solutions are most stable at pH 6.5, as a pH >7 will greatly reduce thrombin activity. Since thrombin solutions adsorb to glass, it is recommended to aliquot solutions in plastic tubes and store at –20 ºC for long-term storage. Various literature sources indicate solutions may be most stable when stored at -70ºC. The long term stability of this product in solution has not been established.
