What does HEPES solution do?
Specifically, HEPES buffer is used to maintain the ideal conditions for cell culture. Therefore, it’s classed as a biological buffer and is best suited for microbiology and histology. It’s also useful in medicine as part of diagnostic laboratory procedures.
Does HEPES expire?
HEPES sodium salt is stable at least three years if stored sealed and kept dry at room temperature. Although Sigma does not assign expiration dates, sodium HEPES should be re-evaluated for continued suitability in user application every three to five years.
Is HEPES water soluble?
Water
HEPES/Soluble in
Why is HEPES used?
HEPES is widely used in cell culture, largely because it is better at maintaining physiological pH despite changes in carbon dioxide concentration (produced by aerobic respiration) when compared to bicarbonate buffers, which are also commonly used in cell culture.
How do you store hepes solution?
Once the pH of the solution is 7.4, add enough deionized water to raise the volume to 100 mL. Sterile-filter, if possible, and store in the refrigerator for up to 4 months or aliquot and freeze at -20 C for future use.
How do you make a HEPES Koh buffer?
HEPES Buffer (1 M, 7.5 pH) Preparation and Recipe
- Prepare 800 mL of dH2O in a suitable container.
- Add 238.3 g of HEPES to the solution.
- Adjust solution to desired pH by 10N NaOH.
- Add dH2O until volume is 1 L.
What is HEPES buffer pH?
HEPES has been described as one of the best all-purpose buffers available for biological research. 4 At most biological pHs the molecule is zwitterionic, and is effective as a buffer at pH 6.8 to 8.2.
What is the pH of HEPES?
6.8 to 8.2

What is HEPES buffered saline?
HEPES Buffered Saline Solution (BSS), is used to neutralize the complex proteins in growth medium that may inactivate trypsin during trypsinization. HEPES BSS at a fill volume of 100 mL is a component of the ReagentPackTM Subculture kit (catalog number CC-5024).
What is the use of HEPES solution?
It is commonly used to buffer cell culture media in air. HEPES finds its usage in in vitro experiments on Mg. Hank′s balanced salt solution, Dulbecco′s modified eagle′s medium and no-glucose DMEM, which are used for the preparation of tissue slices
What is Hepes buffer used for?
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.
What is the concentration of HEPES used in tissue culture?
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.
