一般說明
X-Gal is a chromogenic substrate used in conjunction with IPTG for blue/white colony selection. It is a soluble colorless compound comprising galactose attached to a substituted indole. In the presence of X-Gal the lac+ bacteria after α-complementation form blue colonies and bacteria carrying recombinant plasmid form white colonies.
