Induction of the lacZ gene with IPTG leads to the hydrolysis of X-Gal and to the development of blue colonies. X-Gal Solution, ready-to-use, is a stable, 0.22μm membrane filtered solution formulated for direct use in conjunction with IPTG for blue/white colony screening.

Recommended for:

Blue/white colony screening to distinguish recombinant (white) from non-recombinant (blue) colonies (1); Visualization of beta-galactosidase reporter gene expression in transfected eukaryotic cells; Detection of beta-galactosidase activity in immunological and histochemical procedures.


Preparation of a 20mg/mL stock solution in dimethylformamide (DMF) or dimethylsulfoxide (DMSO) is recommended for X-Gal. DMF dissolves some plastic materials. The direct addition of DMF-containing solution to plastic Petri dishes should be avoided. DMF is toxic. Allow X-Gal solution containing dimethylformamide to completely dry before plating bacteria on agar plates.



Blauw/witte koloniescreening voor onderscheid tussen recombinante (witte) en niet-recombinante (blauwe) kolonies (1); visualisatie van beta-galactosidase-reporter genexpressie in getransfecteerde eukaryotische cellen; detectie van beta-galactosidase-activiteit in immunologie
