Immunohistochemistry-Paraffin: Nbs1 Antibody [NB100-143] - FFPE human testis using Nbs1 antibody [NB100-143] at 1:200 on a Bond Rx autostainer (Leica Biosystems). The assay involved 20 minutes of heat induced antigen retrieval (HIER) using 10 mM sodium citrate buffer (pH 6.0) and endogenous peroxidase quenching with peroxide block. The sections were incubated with primary antibody for 30 minutes and Bond Polymer Refine Detection (Leica Biosystems) with DAB was used for signal development followed by counterstaining with hematoxylin. Whole slide scanning and capturing of representative images was performed using Aperio AT2 (Leica Biosystems). Staining was performed by Histowiz.

Western Blot: Nbs1 Antibody [NB100-143] - EXO1 influences DNA repair & DNA replication in Nbs1 mutants. (A) Schematic illustration of the SA-GFP based SSA assay. (B) Western blotting of cells transfected with or without a vector expressing human NBS1. The genotypes are abbreviated throughout the figure as follows: wild type = W, Nbs1 deltaB/ deltaB = N, Exo1−/− = E, and Nbs1 deltaB/ deltaB Exo−/− = NE. (C) Quantification of SSA mediated repair plotted as the percentage of GFP positive cells. Values for NE are corrected for the reduced percentage of cells in S/G2 determined by BrdU & PI staining (mean 58% compared to a mean of 73% in the other genotypes). The fold rescue with NBS1 expression is the same in N & NE (2.2 fold). (D) Measurement of replication tract lengths following CldU or IdU pulse labeling. (E) Calculation of replication fork velocity in the indicated genotypes (as described in ‘Materials & Methods’ section). Examples of representative forks from W & NE cultures are shown for comparison. (F) Assessment of replication fork restart following 1 mM HU treatment using the indicated scheme. Relative tract ratio is calculated by dividing the length of the IdU tract by that of the CldU tract ( = 2 under unperturbed conditions). Thus, higher values indicate faster restart following HU removal.
