Acide 4-(2-hydroxyéthyl)-1-pipérazinéthanesulfonique

Description :
Acide 4-(2-hydroxyéthyl)-1-pipérazinéthanesulfonique, communément connu sous le nom de HEPES, est un agent tampon zwitterionique largement utilisé dans la recherche biologique et biochimique. Il a une valeur de pKa d'environ 7,5, ce qui le rend particulièrement efficace pour maintenir un pH physiologique dans les cultures cellulaires et les essais biochimiques. HEPES est soluble dans l'eau et présente une bonne stabilité dans des conditions physiologiques, ce qui est crucial pour les expériences nécessitant des niveaux de pH constants. Sa structure présente un cycle de pipérazine, un groupe acide sulfonique et une chaîne latérale d'hydroxyéthyle, contribuant à sa capacité tampon. HEPES est non toxique pour les cellules, ce qui le rend adapté à diverses applications, y compris la purification des protéines et les essais enzymatiques. De plus, il est moins susceptible d'interférer avec les processus biologiques par rapport à d'autres tampons, tels que les tampons phosphate. Cependant, il est important de noter que HEPES peut absorber la lumière UV, ce qui peut affecter certaines analyses spectroscopiques. Dans l'ensemble, HEPES est un tampon polyvalent et largement utilisé dans les milieux de laboratoire, en particulier dans les domaines de la biologie moléculaire et de la biochimie.
