Storage & reconstitution
Typically supplied as a lyophilized powder; keep sealed vials cold (refrigerated short term, frozen for long-term holding) and away from light. Laboratories commonly reconstitute with bacteriostatic or sterile water, swirling gently rather than shaking, and keep the solution refrigerated, using it within a few weeks.
