Non-radioactive chemically-labeled polynucleotide probes, such as non-radioactive chemically-labeled, single- stranded DNA probes, are hybridized to fixed, denatured, single-stranded genetic material having a make-up complementary to said probes for determining the identification and/or presence of said genetic material. The non-radioactive chemical label on said probe is employed to elicit a response therefrom so as to determine the identity and/or presence of said genetic material. It is preferred that the non-radioactive chemical label attached to the probe have an enzyme attached thereto after hybridization, and that the presence of the enzyme attached to the chemically-labeled probe be elicited by spectro-photometric assay techniques.

in techniques for the analysis of genetic material, such as DNA and/or RNA, wherein the genetic material is denatured, fixed to a substrate and hybridized with a probe, superior results are obtainable when there is employed as the probe a chemically labeled probe which, preferably after hybridization, has added or attached thereto, such as to the chemical label or moiety of the probe, an enzyme component effective upon contact with a chromogen to produce an insoluble color precipitate or product. Techniques for the analysis of genetic material which are improved in sensitivity, definition, accuracy and/or speed, by employing a chemically labeled probe, include such well known techniques as «Southern» blot analysis, «Northern» blot analysis, «Western» blot analysis, colony hybridization, plaque lifts, cytoplasmic dot hybridization, in situ hybridization to cells and/or tissues and other such techniques.
The invention relates to ribose- and 2-deoxyribose compounds having the general formula
The definitions of the compounds is given in the claims.
Applications include detection and localization of polynucleotide sequences in chromosomes, fixed cells, tissue sections, and cell extracts. Specific applications include chromosomal karyotyping, clinical diagnosis of nucleic acid-containing etiological agents, e.g. bacteria, viruses, or fungi, and diagnosis of genetic disorders.
