Do you need bulk/larger quantities?
Slow-binding competitive inhibitor of arginase I (Ki=0.4-0.6µM & KD=2.22µM for recombinant rat liver arginase) and arginase II (Ki=0.31µM at pH 7.5 and 0.03µM at pH 9.5 for human recombinant type II arginase). Enhances NO-dependent smooth muscle relaxation in human penile corpus cavernosum tissue. Does not inhibit nitric oxide synthase (NOS) and may serve as a valuable reagent to probe the physiological relationship between arginase and NOS. Inhibitor of rat aortic smooth muscle cell proliferation.
