Hepes media
HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) is a zwitterionic sulfonic acid buffering agent; one of the twenty Good's buffers. 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 cel… WebThe level of HEPES in cell culture media may vary from 10 mM to 25 mM. In Gibco DMEM, HEPES is present at a concentration of 25 mM. However, in Gibco DMEM/F-12 , it is found at a concentration of 15 mM. The most commonly used concentration is 25 mM.

WebHEPES has been described as one of the best all-purpose buffers available for biological research. [ 1] At biological pH, the molecule is zwitterionic, and is effective as a buffer at pH 6.8 to 8.2. HEPES has been used in a wide variety of applications, including tissue culture. It is commonly used to buffer cell culture media in air. Web3 okt. 2024 · HEPES has a pKa = 7.3 (at 37 ° C) and this makes it a good buffer used for cell cultures. As said above, most cells need bicarbonate in their culture medium, therefore HEPES presence as a buffer agent does not completely eliminate the need for bicarbonate in media formulations. HEPES has no nutritional benefit to cells
WebWith the ESIPT property, HL 1 and HL 2 could also detect Zn 2+ ions via the “turn on” mode in EtOH/HEPES media. During the detection process, both demonstrate rapid response and high contrast before and after the addition of metal ions. The species formed in the detection system were investigated.
