Different types of cell culture reagents support cell growth and the consistency of cell culture. Supplements provide additional nutrients to the cells growing in the culture, such as antioxidants, amino acid solutions, and growth factors. Inorganic salts such as calcium chloride dehydrate, potassium chloride, and sodium chloride are used as balanced salt solutions to maintain the medium at physiological pH, intracellular, and extracellular osmotic pressure. All the reagents used in cell cultures are of high quality.
