Apex X-Gal Biotechnology Grade

Apex X-Gal is manufactured under the industry's most stringent quality control procedures to assure lot-to-lot consistency for reproducible results in your laboratory. Apex X-Gal (5-Bromo-4-chloro-3-indolyl-b-D-galactopyranoside) is a chromogenic substrate for b-galactosidase that turns blueupon hydrolysis. It is commonly used for blue/white screening of recombinants when using vectors that support alpha complementation of b-galactosidase.
