This product is an active protein and may elicit a biological response in vivo, handle with caution.
It is recommended to reconstitute the lyophilized protein in sterile deionized water. Solubilise for 30 to 60 minutes at room temperature with occasional gentle mixing. Carrier protein (0.1% HSA or BSA) is strongly recommended for further dilution and long term storage.
