Visualizing unwinding of individual <t>DNA</t> molecules using fluorescent SSB protein and TIRF microscopy. (A) Top: Diagram of phage λ DNA molecule with the indicated number of biotin groups incorporated in each 12-nt cos overhang. Middle: Illustration of biotinylated λ DNA attached at both ends via biotin–streptavidin linkage. Bottom: Image of an actual λ DNA molecule attached to the glass surface, stained with YO-PRO-1 (100 nM), and illuminated with a 488 nm laser. The image is false colored in green and the attachment points to the glass surface are indicated. (B) The process required to construct a flow cell containing three separate single-channels. The steps highlighted are equivalent to those described in Section 4.1. (C) The flow cell from (B) mounted onto the objective; biotinylated <t>lambda</t> DNA was injected under buffer flow, permitting attachment of both ends to the surface. Unwinding tracks are visualized by binding of AF488-SSBG26C (green) to ssDNA regions. (D) Schematic representation of a TIRF microscope capable of visualizing DNA unwinding by RecQ by monitoring signal from both DNA and fluorescent SSB simultaneously. As shown in (C) the flow cell is mounted onto a 100× oil-immersion objective. The fluorescent SSB and DNA are excited by two lasers; 488 and 561 nm, respectively, and emission measured, via dichroic mirrors (M1 and M2). The deconvoluted emission is then directed onto different areas of a CCD camera generating a signal corresponding to either SSB or DNA. The lasers are operated using a custom LABview VI program to coordinate excitation with image acquisition so that the sample is illuminated only during the exposure times.
