IPTG (Isopropyl β-D-thiogalactopyranoside), Dioxane Free, 500g, is a high-purity reagent used to induce gene expression in bacterial systems, particularly E. coli. This large quantity is ideal for high-throughput laboratories or commercial-scale protein expression experiments. IPTG works by binding to the lac repressor, triggering the lac operon and allowing the expression of recombinant genes. The dioxane-free formula ensures that no toxic solvent residues interfere with biological processes. IPTG is critical in the production of recombinant proteins, gene expression analysis, molecular cloning, and other applications in molecular biology and biotechnology research.
