L-NMMA (Tilarginine) is a non-selective and competitive inhibitor of nitric oxide synthase. L-NMMA inhibits three subtypes, namely nNOS, eNOS, and iNOS, and reduces NO production. L-NMMA alleviates mechanical allodynia, thermal hyperalgesia, and choroidal fibrosis. L-NMMA is applicable to research related to nociception, bone cancer pain, and myopia.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
