DescriptionChromogenic β-galactosidase substrate.
- 5–6 X-gal
Chromogenic substrate for β-galactosidase producing a red or magenta insoluble product. Used to determine the presence or absence of a cloned DNA insert in bacteria growing on agar plates. Designed to replace X-Gal in blue-white selection of recombinant bacterial colonies with the lac+ phenotype. Lac+ colonies grown in the presence of Magenta-Gal turn an intense red color, allowing for easy differentiation between lac+ and lac- colonies.

Solubility overviewSoluble in DMSO
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
