Figure 6. DNA polymerase stalling by GQS formation.
Taq polymerase stalling assay in presence of LiCl, NaCl, KCl or (NH4)2SO4 with control (CT) vs mutated (MCT) oligos using biotinylated primers (Primer). Amplified products were loaded on 15% denaturating urea-PAGE transferred to biodyne B membrane and blotted with avidin-HRP. Arrowheads indicate full-length product, FLP; truncated products, TP and biotinylated-primer, Primer. All the gels were run under the same experimental conditions and blots are presented by using cropped images.
