Description: Supplemental Video 7: Direct imaging of nucleation and growth of RecA on SSB-coated ssDNA using TIRF microscopy. nThis video first shows a flow-extended single molecule of 3′-biotinylated λ ssDNA coated with a fluorescent protein, SSBAF488. The molecule was tethered to a streptavidin-coated glass surface within a microfluidic flow cell and visualized using total internal reflection fluorescence microscopy. Solution flow is left to right. SSBAF488 was exchanged with non-fluorescent SSB on the
