DNA Binding in High Salt: Analysing the Salt Dependence of Replication Protein A3 from the Halophile Haloferax volcanii
Figure 4
(a) SDS-PAGE analysis of 2.5 μg purified HvRPA3-NTD, HvRPA3-CTD-1, and HvRPA3-CTD-2. The 6xHis-tagged constructs have predicted MWs of (HvRPA3-NTD) and (HvRPA3-CTD). (b) Predicted MWs ( axis, ) from size exclusion chromatography analysis of HvRPA3-NTD, HvRPA3-CTD-1, and HvRPA3-CTD-2 in 0.2, 1, and 3 M KCl (light, mid, and dark grey, resp.). HvRPA3-NTD in complex with 18mer ssDNA is also shown.
