Bicarbonate-13C sodium

Bicarbonate- ¹³C sodium is the ¹³C-labeled Sodium bicarbonate (HY-Y0756). Sodium bicarbonate is an inorganic salt that is neutral to slightly alkaline and easily decomposes when exposed to moisture in the air. Sodium bicarbonate can maintain the pH of the culture medium, thereby affecting the expression of inducible nitric oxide synthase (iNOS) and nitric oxide (NO) production in macrophages and reversing the acidosis of the tumor microenvironment. Sodium bicarbonate is widely used in the fields of food, medicine, cosmetics, etc. Its main uses include buffers, flavoring agents, disinfectants, pharmaceuticals, and proton gradient regulators. Sodium bicarbonate is also commonly used as an antacid to inhibit gastrointestinal diseases, neutralize gastric acid, and reduce gastric discomfort .

L-Arginine 20+ Cited Publications		Solubilizing Agents
L-Arginine ((S)-(+)-Arginine) is the substrate for the endothelial nitric oxide synthase (eNOS) to generate NO. L-Arginine is transported into vascular smooth muscle cells by the cationic amino acid transporter family of proteins where it is metabolized to nitric oxide (NO), polyamines, or L-proline. L-Arginine is a potent vasodilator, and can be used to induce experimental acute pancreatitis .
