Fig. 1From: DNA looping by two 5-methylcytosine-binding proteins quantified using nanofluidic devicesa Agarose gel electrophoresis for verification of cytosine methylation. Lane 1 is a DNA ladder, lane 2 is methylated \(\lambda\)-DNA, and lane 3 is unmethylated \(\lambda\)-DNA. Methylated \(\lambda\)-DNA was not digested by HpaII (lane 4), while the unmethylated \(\lambda\)-DNA was digested by HpaII (lane 5). b SDS-PAGE demonstrating purity of proteins used in experimentsBack to article page
