Anti-Rhp51 (fission yeast) rabbit serum

Immunized Animal; Rabbit

Polyclonal antiserum

Cat. No. 63-002, 250 μL


Rhp51 protein of Schizosaccharomyces pombe (fission yeast) is a functional and structural homolog of E. coli RecA protein and the Rad51 proteins of eukaryotes. These proteins play a major role in genetic recombination and recombination repair by mediating strand exchange reaction between homologous DNA strands (1).
The product was prepared by immunizing rabbit with full-size recombinant Rhp51 protein expressed
in E. coli and purified.
Using this anti-serum, the Rhp51 protein (40 kD) in the crude extract was detected by Westernblotting (Fig 1) and Rhp51 foci formation, induced by stalled replication (2) and DNA-damage (3), was
detected by indirect immunofluorescence. GFP-tagging of Rhp51 protein at either N- or C- terminus inactivates the function of Rhp51, and therefore, cannot be used for the study of foci formation instead of the antibody. This antibody was also successfully used for immunoprecipitation (4).
