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.

Application

HEPES buffered saline has been used:
  • for the preparation of plasmid DNA
  • as a reagent to prepare transfection master mix for DNA construct vectors
  • to develop hydrogel precursor for cell leakage assay
