生物活性

Crocetin (Transcrocetin) is an aglycone of crocin. Crocetin is an orally active and brain-penetrant. Crocetin shows strong NMDA receptor affinity and channel opening activity. Crocetin can downregulate the proinflammatory cytokines and COX-2 exoression. Crocetin can inhibit apoptosis and activation of MAPK. Crocetin can delay delays brain and body aging. Crocetin can be used for the researches of cancer, neurological disease and inflammation, such as cervical cancer and ischemia[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.
