Q&A and Customer Reviews


Can I test this kit with skin tissue?

Thanks for your inquiry. Sorry we did not ever use this kit to test skin tissue samples before.
We suggest you do a pretest first if you want to have a try.

Target Data

Function Produces nitric oxide (NO) which is implicated in vascular smooth muscle relaxation through a cGMP-mediated signal transduction pathway. NO mediates vascular endothelial growth factor (VEGF)-induced angiogenesis in coronary vessels and promotes blood clotting through the activation of platelets.
