  • Method for preparing and hybridizing specific probes
    Patent number: 5888734
    Abstract: A method of in situ hybridization (ISH) between nucleic acid or polyamide nucleic acid probes and chromosomal nucleic acid targets is taught, as well as, a kit for perform the method. In the inventive method the chromosomal nucleic acid targets are detected without any chemical or physical pretreatment of the chromosomal nucleic acid targets.
