Stability and Storage
Shipped at 4°C. Store at +4°C short term (1-2 weeks). Store at -20°C or -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). Working aliquots stored with a carrier protein are stable for at least 3 months at -20°C to -80°C..
pH: 7.40
Constituents: PBS, 5% Trehalose
Lyophilized from 0.22 µm filtered solution.
5-10% trehalose is commonly used for freeze drying, and after reconstitution, the trehalose is mostly about 3-5%This product is an active protein and may elicit a biological response in vivo, handle with caution.
-
ReconstitutionReconstitute with sterile deionized water to a concentration of 600 µg/ml.
