Products Description
Uses of HEPES Sodium Salt CAS 75277-39-3
1) HEPES Sodium Salt is used as a buffer system for cell culture, commonly used at working concentrations of 10-25MM; it shows better pH control in tissue or organ culture than inorganic bicarbonate buffer systems. Unlike bicarbonate, HEPES does not provide nutrients to cells. It is only added to the culture medium to enhance buffering capacity when cells need to be processed for long periods of time in a CO2 incubator.
2) Used as an amphoteric electrolyte solution; HEPES dissolves amphoteric electrolytes to prepare pH gradients less than 1 pH unit wide for isoelectric focusing electrophoresis experiments;
3) HEPES can be used as a suitable buffer system for electron microscope observation of protein deposition techniques because it does not negatively affect metal substrates;
4) CAS 75277-39-3 HEPES Sodium Salt can be used as a buffer reagent for quantitative and selective determination of antigen-antibody reactions.
