Fig. 2From: Contribution of nonconsensus base pairs within ArsR binding sequences toward ArsR-DNA binding and arsenic-mediated transcriptional inductionComparison of biotin-labeled probes in protein binding with EMSA. Biotin-labeled probes (1) were mixed with lysates prepared from untreated control cells (2) or arsenic treated cells (3) respectively and subjected to EMSA. a: Probe ECBS-AFBS was compared with AFBS-ECBS. b: Probe ECBS-CS was compared with CS-ECBSBack to article page
