Krebs-Ringer Solution (HEPES-buffered) is a physiological buffer that is widely used in cell culture and tissue maintenance. It is composed of inorganic salts and a buffering agent (HEPES), ensuring that cells are provided with necessary ions while maintaining a stable pH and osmotic balance for optimal cell function. Its balanced formulation is designed to preserve the structural and physiological integrity of cells, making it valuable for biological research and experimental applications.
