:Isopropyl β-D-thiogalactopyranoside
Description :
Isopropyl β-D-thiogalactopyranoside (IPTG) est un composé synthétique couramment utilisé en biologie moléculaire comme inducteur de l'expression génique. C'est un galactoside, spécifiquement un thiogalactoside, ce qui signifie qu'il contient un atome de soufre à la place de l'oxygène dans la partie galactose. L'IPTG est structurellement similaire au lactose et est reconnu par le système de l'opéron lac chez les bactéries, en particulier Escherichia coli, où il se lie au répresseur lac, entraînant l'activation des gènes sous le contrôle du promoteur lac. Cette propriété fait de l'IPTG un outil précieux pour les chercheurs dans les études d'expression des protéines. Le composé est généralement fourni sous forme de poudre cristalline blanche et est soluble dans l'eau, ce qui facilite la préparation de solutions pour un usage expérimental. L'IPTG est stable dans une gamme de conditions, bien qu'il doive être stocké dans un endroit frais et sec pour maintenir son intégrité. Son utilisation est répandue dans le clonage et la technologie de l'ADN recombinant, facilitant la production de protéines pour des applications de recherche et thérapeutiques.

Isopropyl-β-D-thiogalactopyranoside, <5ppm dioxane
CAS :<p>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.</p>Formule :C9H18O5SDegré de pureté :Min. 99.0 Area-%Masse moléculaire :238.30 g/molIsopropyl-β-D-thiogalactopyranoside, approx. 15.0% dioxane
