Human Rad51 protein is a functional and structural homolog of E. coli RecA protein, which plays a major role in genetic recombination and recombination repair by mediating strand exchange reaction between homologous DNA strands (1). Rad51 functionally and physically interacts with its paralogs, Dmc1, Rad51B, Rad51C, Rad51D, Xrcc2 and Xrcc3, and also with Rad52 in recombination processes. It also interacts with oncogenes and tumor suppressors such as BRACA1, BRACA2, and P53 for the maintenance of genome stability (1). The product was purified (Fig.1) from the eggs laid by immunized chicken with full-size recombinant Rap51 protein expressed in E. coli and purified.

IgY antibody shows significantly less backgrounds than IgG antibody of mammals in immuno-reactions

Fig. 3. Detection of Rad51 protein foci formation with the anti-Rad51 antibody in X-ray irradiated human fibroblast cells, GM0637.
  1. The cells were irradiated with X-ray at 2 Gy, grown for 1 hr, fixed with 4% paraformaldehyde for 10 min and washed with PBS three times.
  2. Permeabilized by treatment with 0.5% Triton for 5 min and washed with PBS three times.
  3. Incubated with the anti-Rad51 antibody at 1/100 dilution (left panel) or 1/1,000 dilution (right panel) for 30 min at 37℃ and washed with PBS three times.
  4. As the second antibody, Alexa488-conjugated anti-chicken IgY antibody was used at 1/5,000 dilution.
  5. DNA was stained with Hoechst for 1 min and mounted.

This antibody has been used in the following publication.
