生物活性

Tolvaptan is a selective, competitive and orally active vasopressin receptor 2 (V2R) antagonist with an IC50 of 1.28 μM for the inhibition of arginine vasopressin (AVP)-induced platelet aggregation. Tolvaptan induces cell apoposis and affects cell cycle. Tolvaptan can be used for the research of hyponatremia[1][2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
