Creative BioMart provides quality recombinant proteins, diagnostic antibodies and antigens, diagnostic enzymes and pharmaceutical enzymes to the research community of biology, clinical research, molecular diagnostics and biopharmaceutical drug development.The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20℃. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20℃. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.http://www.creativebiomart.net/description_6160_7.htm
