ABSTRACT
By means of DNA recombinant techniques, the fragment of MYO minisatellite DNA probe 0b-tained from plasmid pUC19 - MYO was inserted into plamsid pGEM - 4Z containing RNA poly-merase promotor, thus a sub-clone pGEM- 4Z-MYO was constructed then. It provided the RNAprobe for the DNA fingerprinting and laid a foundation for raising the sensitivity of detecting the poly-morphism of the minisatel1ite DNA.
ABSTRACT
The initial study of the tumour DNA fingerprints using MYO minisatellite DNA probe wascarried out,and then,by means of DNA recombinant techniques,the fragment of MYO min-isatellite DNA probe obtained from plasmid pUC19-MYO was inserted into plasmid pGEM-4Z containing RNA polymerase promotor,thus a sub-clone refferred as pGEM-4Z-MYOwas constucted.That made an offer of the conditions of preparing RNA probe in order to in-cerase the sensitivities of DNA fingerprinting and laid a foundation for raised the efficiency of de-tecting the polymorphism of the minisatellite DNA.
