Fig. 2From: Metagenomic analyses reveal phylogenetic diversity of carboxypeptidase gene sequences in activated sludge of a wastewater treatment plant in Shanghai, ChinaAgarose gel electrophoresis analysis of PCR products amplified by degenerate primers with metagenomic DNA isolated from activated sludge samples as templates. M1 1-kb plus DNA ladder, M2 100-bp DNA ladder. The CG, CFC, and CFA are amplicons yielded by the degenerate primers CG-F and CG-R, CFC-F and CFC-R, and CFA-F and CFA-R, respectivelyBack to article page
