生物活性

Phosphocreatine (creatine phosphate) is an organic compound found in vertebrate skeletal muscles. Phosphocreatine enhances antioxidant activity, and activates the TAK1 pathway to protect the heart. Phosphocreatine normalizing mitochondrial function and reducing oxidative stress via Akt mediated Nrf2/HO-1 pathway. Phosphocreatine provides renal protection by suppressing Apoptosis and ROS (Reactive Oxygen Species) generation through ERK mediated mediated Nrf-2/HO-1 pathway.[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.
