  The LacZ alpha gene is one of the structural genes present on the Lac Operon in Escherichia coli bacteria . When transcribed by RNA polymerase , the LacZ alpha gene codes for β-galactosidase , an enzyme responsible for the hydrolysis of β-galactosides (e.g. 2-Nitrophenyl β-D-galactopyranoside (ONPG) )

LacZ alpha

An alpha peptide chain encoded by a gene LacZ


Usage and Biology

Mechanism:


Form 1 The ABS350 of reaction solution of bacterial culture and ONPG


Fig1. The ratio of ONPG is 1:2,1:4,1:8,1:10,1:15,1:20 from the left to righ

From the figure 7 the color of the third group is enough obvious compared to the background, and at the same time, in order to balance the principle of economy, the ratio of bacterial culture (OD650=0.5) to TMB was designed to be 1:10.
