Description

In Vitro

nor-NOHA (0.1-1 mM, 72 h) induces apoptosis in a dose-dependent manner under hypoxia (1.5% O2) in K562 cells^[1]. nor-NOHA (1 mM, 72 h) attenuates hypoxia-mediated resistance towards imatinib in K562 or KCL22 cells^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

nor-NOHA (100 mg/kg, i.v., once time) induces a significant reduction of infarct size in male Sprague-Dawley rats^[2]. nor-NOHA (100 mg/kg, i.v., once time) increases plasma citrulline and nitrite levels and decreases the ornithine plasma levels in male Sprague-Dawley rats^[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.
