lacZ alpha

Part Description

The LacZ-alpha fragment is encoded by this region and is derived from the pUC19 cloning vector. Because it is smaller than the LacZ-omega region, the LacZ-alpha fragment can be easily incorporated into a plasmid when the two non-functional LacZ gene fragments (alpha and omega) are co-expressed. X-gal (5-bromo-4-chloro-3-indoyl-d-galactopyranoside), a soluble colourless molecule that is a substrate of ß-galactosidase and generates a blue product when cleaved, is used to detect the alpha-complementation

Usage

alpha domain of ß-galactosidase (our reporter protein) which is produced in response to high levels of phenylalanine and generates a blue product when X-gal is cleaved which is a soluble colorless molecule that is a substrate of ß-galactosidase and generates a blue product when cleaved, is used to detect the alpha-complementation
