Samples were collected and placed on ice in a lysis solution [50 mM Tris–HCl (pH 8.0), 150 mM NaCl, 1 mM EDTA, 1% NP-40, 10% glycerol] containing 0.5% SDS and 2 mM PMSF with a
protease inhibitor cocktail (Sigma P-8340, 1:100). Cellular proteins were resolved on a 12.5% SDS–PAGE gel. The membrane was incubated for 1 h at room temperature in 5% skim milk in PBS with 0.05% Tween-20 (PBST), and the membrane was probed with
anti-PCNA PC10 (Ref # sc56; Santa Cruz),
anti-alpha tubulin (Ref# MA1-80017; Thermo Fisher Scientific),
anti-actin (Ref #MA1-744; Thermo Fisher Scientific), anti-Vinculin (clone 7F9, Ref# 14-9777-80; eBioscience),
anti-AID (Ref #14-959-82; Thermo Fisher Scientific),
anti-polη (Ref# ab17725; Abcam),
anti-FancD2 (Ref# sc20022; Santa Cruz), anti-USP1 (Ref # ab108104Ref; Abcam), anti-Msh2 (Ref #A300-451A; Bethyl), and
anti-Msh6 (Ref # A300-022A; Bethyl) antibodies. Immunoreactivity was detected using a horseradish peroxidase-conjugated secondary antibody.
