Formulation & Storage: It was lyophilized from sterile 10 mM sodium phosphate ( pH 7.4) and we recommend that the powder be reconstituted in sterile 10 mW-cm H2O. Upon reconstitution aFGF should be stored at 4°C. For long-term storage at -20°C, it is recommended to add a carrier protein (0.1% HSA or BSA). Freeze-thaw cycles should be avoided.
Usage: The product is for research only and may not be allowed for usage as drugs, agricultural or pesticidal products, food additives or household chemicals.
