Abstract (en)

[origin: WO8505685A1] A hybridization method for treating target DNA fragments to identify known genetic sequences comprises the following steps: disposing the target DNA fragments on a carrier, either a dried gel film or a blotting matrix to which the target DNA fragments are transferred by the southern blotting technique or a variation thereof; forming a hybridization reagent consisting of a radioactive-labelled probe DNA and catalyzing enzymes and cofactors; immersing the carrier in the hybridization reagent for a given period of time; washing the carrier in at least one wash solution; exposing an x-ray film to the carrier; and developing the x-ray film to detect and locate the radioactive-labelled probe DNA. The catalyzing enzymes utilized in forming the hybridization reagent include RecA protein and SSB DNA binding protein in the presence of ATP.
