## Overview

IPTG (Isopropyl-β-D-thiogalactopyranoside) is a high-purity biochemical reagent used in molecular biology to induce and detect lac operon activity. Supplied as a compact 1 gram bottle, it enables clear differentiation of recombinant colonies in cloning assays, compatible with multiple lacZ-containing vectors. Ideal for research and manufacturing applications, this dioxane-free product from RPI Corp guarantees reliable, contamination-free performance.

## Description

IPTG is combined with X-GAL to detect lac colonies or cells in a colorimetric assay. Distinguishes recombinants (white) from non- recombinants (blue) in cloning strategies using vectors such as Lambda-11, M13mp 18 and 19, pUC18 and 19, pUR222 containing the lacZ gene.
