Acido 4-(2-idrossietil)-1-piperazinaetansolfonico

Descrizione:

Acido 4-(2-idrossietil)-1-piperazinaetansolfonico, comunemente noto come HEPES, è un agente tampone zwitterionico ampiamente utilizzato nella ricerca biologica e biochimica. Ha un valore di pKa intorno a 7,5, rendendolo particolarmente efficace per mantenere il pH fisiologico nelle colture cellulari e nei saggi biochimici. HEPES è solubile in acqua e mostra buona stabilità in condizioni fisiologiche, il che è cruciale per esperimenti che richiedono livelli di pH costanti. La sua struttura presenta un anello di piperazina, un gruppo acido solfonico e una catena laterale di idrossietile, che contribuiscono alla sua capacità tampone. HEPES è non tossico per le cellule, rendendolo adatto per varie applicazioni, inclusa la purificazione delle proteine e i saggi enzimatici. Inoltre, è meno soggetto a interferire con i processi biologici rispetto ad altri tamponi, come i tamponi fosfato. Tuttavia, è importante notare che HEPES può assorbire luce UV, il che può influenzare alcune analisi spettroscopiche. In generale, HEPES è un tampone versatile e ampiamente utilizzato in contesti di laboratorio, in particolare nei campi della biologia molecolare e della biochimica.
