Isopropyl-β-D-thiogalactopyranosid

Beschreibung:

Isopropyl-β-D-thiogalactopyranosid (IPTG) ist eine synthetische Verbindung, die häufig in der Molekularbiologie als Induktor der Genexpression verwendet wird. Es ist ein Galactosid, spezifisch ein Thiogalactosid, was bedeutet, dass es ein Schwefelatom anstelle des Sauerstoffs im Galactoseanteil enthält. IPTG ist strukturell ähnlich wie Laktose und wird vom lac-Operon-System in Bakterien, insbesondere Escherichia coli, erkannt, wo es an den lac-Repressor bindet und zur Aktivierung von Genen unter der Kontrolle des lac-Promotors führt. Diese Eigenschaft macht IPTG zu einem wertvollen Werkzeug für Forscher in der Proteinexpressionsforschung. Die Verbindung wird typischerweise als weißes kristallines Pulver geliefert und ist in Wasser löslich, was die Vorbereitung von Lösungen für experimentelle Zwecke erleichtert. IPTG ist unter einer Vielzahl von Bedingungen stabil, sollte jedoch an einem kühlen, trockenen Ort aufbewahrt werden, um seine Integrität zu bewahren. Seine Verwendung ist weit verbreitet in der Klonierung und der rekombinanten DNA-Technologie, was die Produktion von Proteinen für Forschungs- und therapeutische Anwendungen erleichtert.

IPTG is a gratuitous beta-D-galactosidase inducer. In Escherichia coli IPTG functions by binding to the lac repressor and altering its conformation. This inactivation prevents the repressor binding to the operator of the lac operon and thus the repression of the beta-galactosidase coding gene lacZ. IPTG is a commonly used reagent in cloning procedures that require induction of beta-galactosidase activity and is used in conjunction with X-Gal or Lapis-β-D-Gal in blue-white color selection of recombinant bacterial colonies.
