HEPES, *-(*-Hydroxyethyl)**-Piperazineethanesulfonic Acid, is a
kind of zwitterionic buffer, which is often used in biochemical
experiments to regulate the pH value in the reaction system. For
example, adding HEPES to virus preservation solution or cell
preservation solution is non-toxic to cells and can maintain a
constant pH range for a long time.
HEPES powder is resistant to high temperature and its melting point
is up to **0 ℃. However, HEPES aqueous solution will produce
toxic hydrogen peroxide in the light environment. Therefore, the
use and preservation of HEPES aqueous solution should pay attention
to shading and avoiding light.
HEPES is widely used, mainly in the following aspects:
1. For cell culture: the decomposition ability of HEPES is less
affected by the temperature change, which makes HEPES maintain the
structure and function of enzyme at low temperature.
2. For the study of metal ions: HEPES buffer is often used in the
study of various metal ions. Based on the characteristics of the
buffer, HEPES can better replace Tris and phosphate buffer in the
study of metal ions.
3. For skin care products: HEPES is harmless to human body, safe
and stable, and its pH maintaining property can help skin care
products maintain the activity of microbial fermentation extract
and prolong the efficacy; HEPES can promote the absorption of
various components in skin care products, and improve the skin's
absorption rate of cosmetics; HEPES can also soften cutin, enhance
cell metabolism, and cooperate with sunscreen.
4. For virus preservation solution: HEPES can be used for non
inactivated virus preservation solution. The maintenance of
solution pH by HEPES can increase the survival time of virus host
cells in vitro and maintain the integrity of virus nucleic acid and
protein to the greatest extent.
5. For the preparation of gold nanoparticles: hepes-naoh reduction
method is used to prepare gold nanoparticles based on the reduction
of excessive metals by HEPES at a specific pH value. This method is
simple and rapid.
6. For cell preservation medium: cell culture medium generally
relies on sodium bicarbonate and CO2 for buffering, but CO2 is
unstable in the solution, easy to escape, resulting in increased
pH. In this case, the addition of HEPES can improve the above
problems and maintain a stable pH value of the culture medium.
Our company can produce HEPES buffer products with excellent
quality and reasonable price. For more information, please contact
