CAS 367-93-1 — IPTG (Isopropyl-beta-D-thiogalactopyranoside)

IPTG (Isopropyl-beta-D-thiogalactopyranoside) is a molecular biology reagent used to induce gene expression in bacterial systems, particularly in lac operon-based expression vectors. It is a non-metabolizable analog of allolactose that binds to the lac repressor, allowing transcription of target genes. CAS: 367-93-1, Molecular Formula: C9H18O5S, Molecular Weight: 238.30 g/mol, Storage: 2 to 8 °C, Signal Word: Warning. Molekula supplies IPTG from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
