Biolegend, 626753, Alexa Fluor® 647 anti-NOS3 (eNOS) Antibody, 25μg

Nitric oxide synthase 3 (NOS3), also commonly known as endothelial nitric oxide synthase (eNOS), is a critical enzyme primarily found in the endothelial cells lining the blood vessels. Its main function is to catalyze the formation of nitric oxide (NO) from L-arginine. NO is a signaling molecule with profound effects on vascular health and overall physiology, regulating blood vessel tone and diameter in response to various physiological cues including shear stress, neurotransmitters, and hormones. NO relaxes and dilates blood vessels, thereby promoting proper blood flow and reducing blood pressure. Additionally, NOS3-derived NO helps prevent the formation of blood clots, reduces inflammation in the blood vessel walls, and maintains vascular homeostasis, contributing significantly to cardiovascular health. Dysfunction or impaired activity of NOS3 is implicated in various cardiovascular diseases, making it an important target for therapeutic interventions aimed at preserving vascular function.
