MYO minisatellite DNA probe and sub—cloning of MYO fragment / 中国免疫学杂志

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.
