Product Introduction
HEPES is an important hydrogen ion buffer that has good buffering ability in the pH range of 6.8 to 8.2, and can control a constant Chemicalbook pH for a long time. A concentration of 10-50mmol/L and a general culture medium containing 20mmol/L of 4-hydroxyethyl ethanesulfonic acid can provide good buffering ability and have no toxic effects on cells.

usage method

(1) Hepes buffer can be directly added to the prepared culture medium according to the required concentration, and then filtered for sterilization. 2.38 grams of HEPES are added to every 1000ml of culture medium, and after being dissolved, the pH is adjusted to 7.2 with lNNaOH. After filtering for sterilization, it is used. At this time, the concentration of HEPES is 10mmol/L

(2) It can also be prepared into 100x storage solution (lmol/L). Before use, Chemicalbook takes 99ml of culture solution and adds it to 1ml of storage solution. The final application concentration is still 10mmol/L. Preparation method of lmol/L (100x) hepes buffer solution: Dissolve 23.8g of HEPES in 90ml of double distilled water, adjust the pH to 7.5-8.0 with lNNaOH, and then dilute to 100ml with water. Filter and sterilize the solution, then divide into small bottles (2ml/bottle) and store at 4 ºC or -20 ºC
 

Application

HEPES  is a non-ionic amphoteric buffer with high polarity. It is inert to a variety of chemical reagents and enzymes, does not participate in and do not interfere with the biochemical reaction process of the Chemicalbook, and has no inhibitory effect on enzyme chemical reactions. Therefore, it can be specifically used for research on organelle and highly variable, pH sensitive proteins and enzymes.
 

 
Product Advantages

Purity ≥ 99%, good water solubility, stable process, and can ensure that the product appearance is pure white crystal powder.
