X-GAL is a chromogenic substrate used extensively in molecular biology to detect beta-galactosidase activity. Supplied by MilliporeSigma in a quantity of 100 mg, X-GAL is ideal for applications in gene expression studies and bacterial colony screening. When cleaved by beta-galactosidase, it produces a blue color, facilitating easy identification of enzyme activity. This substrate is essential for researchers working with reporter gene assays.
