Sodium bicarbonate, for molecular biology

Sodium bicarbonate, for molecular biology (Sodium hydrogen carbonate for molecular biolog; Soda bicarbonate for molecular biolog) 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[1][2][3][4][5][6].
