Preparation and Storage
Stability and Storage
Shipped at 4°C. Store at -80°C. Avoid freeze / thaw cycle. For long term storage it is recommended to add a carrier protein on reconstitution (0.1% HSA or BSA).
Constituent: 0.2% Trifluoroacetic acid
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 pipette and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized product with sterile water to a concentration of 0.1mg/ml, which can be further diluted into other aqueous solutions.
Tissue specificityHighly expressed in skin (basal and suprabasal layers of the epidermis, hair follicles and endothelial cells). Also found in pancreas, liver, spleen, prostate, ovary, small intestine and colon.
