4-(2-Hydroxyethyl)-1-piperazinethansulfonsäure

Beschreibung:

4-(2-Hydroxyethyl)-1-piperazinethansulfonsäure, allgemein bekannt als HEPES, ist ein zwitterionisches Pufferungsmittel, das in der biologischen und biochemischen Forschung weit verbreitet ist. Es hat einen pKa-Wert von etwa 7,5, was es besonders effektiv macht, um den physiologischen pH-Wert in Zellkulturen und biochemischen Assays aufrechtzuerhalten. HEPES ist in Wasser löslich und zeigt eine gute Stabilität unter physiologischen Bedingungen, was für Experimente, die konsistente pH-Werte erfordern, entscheidend ist. Seine Struktur weist einen Piperazinsring, eine sulfonische Säuregruppe und eine Hydroxyethyl-Seitenkette auf, die zu seiner Pufferkapazität beitragen. HEPES ist nicht toxisch für Zellen, was es für verschiedene Anwendungen geeignet macht, einschließlich der Proteinreinigung und enzymatischer Assays. Darüber hinaus ist es weniger anfällig dafür, biologische Prozesse im Vergleich zu anderen Puffern, wie z.B. Phosphatpuffern, zu stören. Es ist jedoch wichtig zu beachten, dass HEPES UV-Licht absorbieren kann, was bestimmte spektroskopische Analysen beeinträchtigen kann. Insgesamt ist HEPES ein vielseitiger und weit verbreiteter Puffer in Laborumgebungen, insbesondere in den Bereichen Molekularbiologie und Biochemie.
