Isopropyl-beta-D-thiogalactopyranoside CAS:367-93-1

Isopropyl-beta-D-thiogalactopyranoside (IPTG) is widely employed in molecular biology research for its role as an inducer of gene expression. In recombinant protein expression systems, IPTG is used to trigger the activation of promoters controlling the transcription of target genes. By mimicking the natural inducer lactose, IPTG binds to the lac repressor protein, causing its release from the lac operator region on the DNA. This derepression allows RNA polymerase to initiate transcription, leading to the synthesis of recombinant proteins encoded by the target gene. Moreover, IPTG finds utility in the production of recombinant proteins for various applications, including protein purification, structural biology studies, and therapeutic protein production. Its ability to regulate gene expression enables precise control over the timing and level of protein synthesis, facilitating the optimization of protein production processes. Furthermore, IPTG is utilized in the screening of recombinant DNA libraries and the identification of clones containing the gene of interest. In systems utilizing lac promoter-based expression vectors, the addition of IPTG induces the expression of reporter genes or fusion proteins, allowing for the detection and selection of clones carrying the desired DNA sequences. Additionally, IPTG is employed in studies involving gene regulation, cellular differentiation, and signal transduction pathways. Its ability to modulate gene expression provides researchers with a tool to investigate the functions of specific genes and regulatory elements in cellular processes and disease mechanisms. Furthermore, IPTG is used in microbial fermentation processes for the production of recombinant proteins in bacterial hosts such as Escherichia coli. By inducing the expression of target genes, IPTG promotes the synthesis of recombinant proteins within the bacterial cells, which can be subsequently harvested and purified for various biotechnological and pharmaceutical applications. Overall, Isopropyl-beta-D-thiogalactopyranoside (IPTG) serves as a versatile tool in molecular biology research, enabling the controlled expression of target genes and the production of recombinant proteins for a wide range of scientific and industrial purposes. Its applications span from basic research in gene expression regulation to biotechnological applications in protein production and therapeutic protein engineering.
