WebHEPES is a biological buffer often referred to as a “Good′s” buffer. It is the most commonly used biological buffer since the pKa of HEPES is 7.31 which corresponds to the physiological pH of 7.36. HEPES is considered to be non-toxic to culture cell lines, highly water soluble and provides high solution clarity. WebHEPES is a zwitterionic sulfonic acid buffering agent, commonly used to uphold a neutral pH of basal medium within cell cultures. References [1] Baicu SC, et al.
