Solution tampon hepes
WebL'HEPES (ou acide 4-(2-hydroxyéthyl)-1-pipérazine éthane sulfonique) est un composé organique zwitterionique, couramment utilisé sous forme de solution tampon en biochimie.Il fait partie des tampons de Good.Depuis les travaux de Good en 1966, il est largement préféré au tampon bicarbonate pour la culture cellulaire en raison d'une meilleure stabilité … WebHEPES is commonly used in cell culture media as a buffering substance. Compared to the bicarbonate/CO 2 buffer system, it does not require a CO 2 atmosphere, thereby ensuring stable pH values during handling of cell culture media outside of an incubator. Due to its intrinsic charge, HEPES is considered not to be taken up by cells, which was a prerequisite …
