Isopropil β-D-tiogalactopiranosídeo

Descrição:

Isopropil β-D-tiogalactopiranosídeo (IPTG) é um composto sintético comumente usado em biologia molecular como um indutor da expressão gênica. É um galactosídeo, especificamente um tiogalactosídeo, o que significa que contém um átomo de enxofre no lugar do oxigênio na parte de galactose. IPTG é estruturalmente semelhante à lactose e é reconhecido pelo sistema do operão lac em bactérias, particularmente Escherichia coli, onde se liga ao represor lac, levando à ativação de genes sob o controle do promotor lac. Essa propriedade torna o IPTG uma ferramenta valiosa para pesquisadores em estudos de expressão de proteínas. O composto é tipicamente fornecido como um pó cristalino branco e é solúvel em água, facilitando a preparação de soluções para uso experimental. IPTG é estável sob uma variedade de condições, embora deva ser armazenado em um local fresco e seco para manter sua integridade. Seu uso é generalizado em clonagem e tecnologia de DNA recombinante, facilitando a produção de proteínas para aplicações de pesquisa e terapêuticas.

CAS: 367-93-1

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.
