HEPES PUFFERAN® CELLPURE® ≥99,5 %

Extremely versatile buffer. Excellent for cell and tissue cultures and for analysis of biological systems.

Toepassingsvoorbeelden:
  • Combined with bicarbonate, HEPES is an excellent medium for human lymphocytoidal cell lines
  • HEPES is more effective than NaHCO3 when controlling the pH value in tissue and organ culture
  • HEPES-buffered media for chicken and human lung fibroblasts
  • Can be used to replace a bicarbonate buffered medium containing serum with a serum-free HEPES-buffered medium for mouse fibroblasts

Tested for low amount of endotoxins.


Buffer reagent according to Good. High buffer capacity at physiological pH-values.
