Structure of Biotin-14-dATP

DNA polymerase incorporation of biotin-14-dATP via nick translation.
pBR322 DNA modified via a Pol I/DNAse I nick translation assay with a dNTP mix containing Active Motif’s biotin-14-dATP as the ATP source. The reaction was terminated, and the DNA was spin column purified, quantified and spotted on nitrocellulose membrane. Biotin incorporation was assessed by incubating the membrane with HRP-conjugated anti-biotin antibody. A, nick translation with ATP. B and C, nick translation with biotin-14-ATP (biological replicates).

Hi-C Contact Frequency vs. Genomic Distance
Similar Distance-Dependence of Contact Frequency. Hi-C datasets generated using Active Motif’s biotin-14-dATP and another commercial reagent (Rao ref) show a similar distribution of contacts ranging from short- to long-distance, indicating that biotin-based capture using the Active Motif reagent is unbiased.
