IPTG CAS:367-93-1 Manufacturer Price
Isopropyl β-D-1-thiogalactopyranoside (IPTG) is a synthetic analog of lactose that is commonly used in molecular biology research and biotechnology applications. IPTG is primarily used to induce the expression of genes in bacterial systems, where it serves as a molecular trigger to initiate the transcription of target genes.
When added to the growth medium, IPTG is taken up by the bacteria and can bind to the lac repressor protein, preventing it from blocking the activity of the lac operon. The lac operon is a cluster of genes involved in lactose metabolism, and when the repressor protein is removed, the genes are expressed.
