Deoxyribonucleic acid molecules useful as probes for detecting deleterious genes incorporated into chromosomal DNA.

摘要

@ A single-stranded deoxyribonucleic acid molecule having a length of less than about 25 kb comprises at least three distinct nucleotide sequences which are the sites for incorporation into a chromosome of a deoxyribonucleic acid molecule encoding a deleterious gene. Deoxyribonucleic acid probes have been prepared from such molecules and are useful as hybridization probes for detecting chromosomal deoxyribonucleic acid which has a deoxyribonucleic acid molecule encoding a deleterious gene incorporated therein.

A single-stranded deoxyribonucleic acid molecule derived from human chromosome (22) which is about 5.8 kb in length contains sites for incorporation of a deoxyribonucleic acid molecule encoding the oncogene c-ab1 derived from human chromosome (9). Deoxyribonucleic acid probes have been prepared from this molecule and used to detect the abnormal Philadelphia chromosome and chronic myelocytic leukemia.
