Competitors experiments have been performed working with 100fold excess of unlabeled wildtype or mutant oligonucleotides preincubated with all the Isl1 protein at room temperature for ten minutes just before adding the DNA probes. Antibody supershift assays were performed utilizing 1 l of Isl1 antibody (40.2D6, 400 g/mL) preincubated with Isl1 protein at space temperature for 20 minutes before adding the DNA probes. All DNA binding samples were electrophoresed on 6 nondenaturing polyacrylamide gels at one hundred V for 45 minutes in 0.five trisborateEDTA buffer. Gels had been transferred to a nylon membrane at 380 mA for 45 minutes in 0.five trisborateEDTA buffer. The biotinlabeled DNA was detected having a LightShift chemiluminescent EMSA kit (20148; Thermo Scientific).Statistical analysisAdditional filesAdditional file 1: Supplementary Data.
