MCF10A cells were transduced with a lentivirus expressing GFP-MDC1 (pLenti CMV/TO GFP-MDC1). Cells were splitted and 10 000 cells per well were seeded on an eight-well immunofluorescence slide. The slide was irradiated with X-Rays (5 Gy) and incubated for one hour at 37oC. The cells were then fixed with 4% paraformaldehyde and permeabilized with 0.5% Triton X-100 in PBS. The slide was blocked and incubated in the presence of an antibody against the phosphorylated form of H2AX (Gamma-H2AX, clone JBW301, Upstate). An anti-mouse Cy5 secondary antibody (Jackson immunochemicals) was used to detect the gamma-H2AX by immunofluorescence. The endogenous fluorescence of GFP was detected. As reported in the literature, MDC1 co-localizes with gamma-H2AX at sites of DNA damage detected by foci. GFP-MDC1 still localizes at foci in the absence of gamma-H2AX antibody (negative control for cross-reactivity and "channel bleeding"). PDF version of the slide can be downloaded here.
