ABSTRACT:
A method for diagnosing mammalian breast cancer by detecting in the physiological fluid of said mammal an antigen (ACRT) having immune cross-reactivity with human reverse transcriptase, or detecting antibodies against said ACRT or detecting antibody-ACRT complexes, wherein the reverse transcriptase is substantially purified, has a molecular of about 70,000 and a sedimentation coefficient on a glycerol gradient of between 5 and 5.5 S. A process for the purification of reverse transcriptase from human milk.
