Mechanism
A nonapeptide that needs zinc to be active and affects T-cell differentiation.
Research areas
- thymic hormone research
- T-cell differentiation
Storage & reconstitution
Supplied as a freeze-dried (lyophilized) powder in a sealed vial. Unopened vials are generally kept cold and away from light. Labs usually reconstitute it with bacteriostatic or sterile water, letting the liquid run down the vial wall and swirling gently instead of shaking. The solution is then kept refrigerated.
