生物活性

Aristoforin, a hypericin derivative, inhibits the activities of SIRT1 and SIRT2. Aristoforin induces G1 phase cell cycle arrest, scavenges hydroxyl free radicals, and exhibits protective activity against Fe2+-induced DNA breakage. Aristoforin can be used in studies related to breast cancer and colon adenocarcinoma[1][2][3][4].

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.
