Stability and Storage
Shipped at 4°C. Store at -20°C. For long term storage it is recommended to add a carrier protein on reconstitution (0.1% HSA or BSA).
This product is an active protein and may elicit a biological response in vivo, handle with caution.
-
ReconstitutionCentrifuge vial before opening. When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution.
