Figure 1 Colony-lift filter assay for β-galactosidase activity. Left: β-galactosidase activity of AH109 transformed with pGBKT7-ECRG2. Right: β-galactosidase activity of AH109 transformed with pCL1 (positive control). The results showed that pCL1 could activate reporter genes, but pGBKT7-ECRG2 could not.
