Sheep anti Human MDC1 antibody (AHP799) used for the visualization of MDC1 expression in U2OS osteosarcoma cells following irradiation induced DNA damage by immunofluorescence.
Image caption:
PP4 dephosphorylates γH2AX at the sites of DNA damage. (A,B) U2OS cells transfected with siRNAs against PP4C, PP2ACα/β or a control sequence were irradiated with 1.5 Gy and processed for γH2AX (A,B) and MDC1 (B) immunofluorescence and DAPI counterstaining at the indicated time points. Images were taken with a × 40 objective (A) or with a × 63 objective (B). Scale bar, 23 μm (A) and 16 μm (B). (C–F) Quantification of cells with >5 γH2AX (C), >10 γH2AX (D,F) and >5 MDC1 (E) foci. At least 300 cells were analysed per experiment. Cells were treated with KU55933 and KU57788 12 min post-IR (F). Error bars represent standard error of mean of independent duplicated experiments (C) or standard deviation of three independent experiments (D–F). A × 63 oil immersion objective (C,E) or a × 40 water immersion objective (D,F) was used. (G) U2OS cells transfected with siRNAs against PP4C or a control sequence were collected at the indicated time points immediately before (no IR), or 1 or 6 h after irradiation (10 Gy), then fractionated as described in Méndez & Stillman (2000) into whole-cell lysates (WCLs), nuclear soluble (S3) or chromatin (P3) fractions, and analysed by immunoblotting using the indicated antibodies. DAPI, 4,6-diamidino-2-phenylindole; H3, histone H3; IR, irradiation; MDC1, mediator of DNA damage checkpoint 1; siRNA, small interfering RNA.

Analysis of epigenetic differences in meiotic silencing in oocytes compared to spermatocytes. a XY pachytene spermatocyte stained for SYCP3 (magenta), HORMAD2 (green) and MDC1 (red), showing MDC1 accumulation in the sex chromatin (arrow). b XO pachytene oocyte stained for SYCP3 (magenta), HORMAD2 (green) and MDC1 (red), also showing MDC1 enrichment on the asynapsed X chromosome (arrow). c XY pachytene spermatocyte stained for SYCP3 (magenta), HORMAD2 (green) and SUMO-1 (red), showing accumulation of SUMO-1 in the sex chromatin (arrow). d XO pachytene oocyte stained for SYCP3 (magenta), HORMAD2 (green) and SUMO-1 (red), also showing SUMO-1 enrichment on the asynapsed X chromosome (arrow). e XY diplotene spermatocyte stained with SYCP3 to mark chromosome axes (magenta), HORMAD2 (green) to label the asynapsed X and Y chromosomes (arrow) and H3K9me3 (red), which shows enrichment in the chromatin of the X and Y chromosomes and also at constitutive heterochromatin (asterisks). A line (yellow) was drawn through the asynapsed X (arrow) to quantify HORMAD2 and H3K9me3 intensities (g). f XO diplotene oocyte showing no enrichment of H3K9me3 in the chromatin of the asynapsed X chromosome (arrow). H3K9me3 staining is restricted to sites of constitutive heterochromatin (asterisks). A line (yellow) was drawn through the asynapsed X (arrow) to quantify HORMAD2 and H3K9me3 intensities (h). g, h Intensities of H3K9me3 and HORMAD2 immunostaining quantified by densitometry across the indicated paths along (g) the asynapsed X in the spermatocyte from panel e, and along (h) the asynapsed X in diplotene XO oocyte from panel f.

    • Sheep anti Human MDC1 antibody recognizes human Mediator of DNA damage checkpoint protein 1, also known as MDC1 or Nuclear factor with BRCT domains 1. MDC1 is a 2089 amino acid, ~250 kDa nuclear protein containing two BRCT domains and a single FHA domain. MDC1 is involved in checkpoint mediated cell cycle arest in response to DNA damage (UniProt: Q14676)
