Description

Descripción general

HEPES buffer does not confer cytotoxic effects on cells and thus can be used in animal cell cultures.[1]

HEPES has been described as one of the best all-purpose buffers available for biological research.[2] At biological pH, the molecule is zwitterionic, and is effective as a buffer at pH 6.8 to 8.2. HEPES has been used in a wide variety of applications, including tissue culture. It is commonly used to buffer cell culture media in air. HEPES finds its usage in in vitro experiments on Mg.[3]

Aplicación

HEPES has been used:

• To supplement Dulbecco′s modified Eagle′s medium to culture and maintain cell lines[4][5]
• As a component of platelet suspension buffer[6]
• To supplement Hank′s basic salt solution, which is used to wash pancreatic tissue[7]
• As a component of wash buffer and blocking buffer in the purification and quantification of protein with enzyme-linked immunosorbent (ELISA) assay[8]
• For the adjustment and maintenance of pH of biological solutions[8]
• As a component of Hank′s balanced salt solution (HBSS) and dissociation medium to study neuronal development[9]
• For homogenization of tissue and in the preparation of cytosolic and nuclear extract from cells[10]
• As a component of keratinocyte and fibroblast culture medium[11]
