Human Endogenous Metabolite

 

Microbial Metabolite

 

In Vitro

L-Ornithine (0-10 mM) activates the CaSR in a concentration-dependent manner and exerts effects on Ca2+ signaling in HK-2 cells[2].
L-Ornithine (10 mM) activates TRPC channels mediated Ca2+ entry pathway in HK-2 cells[2].
L-Ornithine (100 or 300 μM; 24 h) shows the protection against ROS generation in HK-2 cells via ROCE pathway[2].
L-Ornithine (10 μM) can protect the ROS and oxidative damage in HK-2 cells exposed to H2O2[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.
