(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 1 8 . 9 × 1 0 3 (HvRPA3-NTD) and 1 7 . 6 × 1 0 3 (HvRPA3-CTD). (b) Predicted MWs ( 𝑦 axis, × 1 0 3 ) 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.
