Merck, H7006-500G, HEPES sodium salt

HEPES salt, or 4-(2-hydroxyethyl)piperazine-1-ethanesulfonic acid sodium salt, is a zwitterionic biological buffer that is widely used in biological and biochemical research. It has a buffering range of pH 6.8 to 8.2, making it ideal for a variety of research applications. HEPES is also a popular choice for buffering cell culture media, offering advantages such as lower cell toxicity in comparison to alternatives like Tris and phosphate. Widely utilized in cell biology and biochemical research, HEPES proves its versatility in protein purification and extraction protocols, owing to its stability across a broad pH range and minimal metal ion binding. Additionally, HEPES proves valuable in various biological and biochemical processes, including immunoprecipitation, cell lysis, and live cell imaging, making it a versatile tool in diverse research applications.
