HEPES Chemical Properties,Uses,Production
Description
HEPES has been described as one of the best all-purpose buffers available for biological research. At biological pH, the molecule is zwitterionic, and is effective as a buffer at pH 6.8 to 8.2 (pKa 7.55). It is typically used in cell culture at concentration between 5mM to 30 mM. 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.
Chemical Properties
White crystalline powder
Uses
Non-toxic to cell. It is used as a hydrogen ion buffer, which can control the constant pH range for long term. The concentration is 10-50mmol/L. Generally, 20mmol/LHEPES in nutrient solution can get buffer ability.
Uses
HEPES is a biological buffer. It may be used in isoelectric focusing applications and as a buffer in the quantitative and selective measurement of antigen-antibody reactions. HEPES is reportedly superior to NaHCO3 in controlling pH in tissue and organ culture. HEPES is not recommended for use with the Folin-Ciocalteu protein assay.
Definition
ChEBI: A HEPES that is ethanesulfonate substituted by a 4-(2-hydroxyethyl)piperazin-4-ium-1-yl group at position 2.
General Description
HEPES buffered saline is a tissue culture buffer, which is used to maintain the pH of cell culture. It is water soluble and atmosphere independent. HEPES destroys magnesium in sodium chloride solutions.
Biological Activity
HEPES is a multi purpose HEPES buffer used in cell culture and other biological research. Working pH range in aqueous solution: 6.8 - 8.2. Does not form complexes with metal ions. Used in cell culture media.
Purification Methods
Crystallise the acid from hot EtOH and water. It is a useful buffer. [Beilstein 23 V 376.]
