  • Method for the measurement of reverse transcriptase using immobilized primer
    Patent number: 5508166
    Abstract: A method is provided for the determination of the presence of a reverse transcriptase in a sample liquid. In an aqueous medium, at least an adenine ribopolynucleotide RNA template (poly A), an immobilized oligodeoxythyminenucleotide and a biotinylated deoxyuridine triphosphate are reacted in the presence of the sample liquid. After separation of the reacted and the unreacted biotinylated deoxyuridine triphosphate from each other, the reacted or the unreacted biotinylated deoxyuridine triphosphate is detected. Also provided is a method for the determination of infection of a patient to a retrovirus. The reaction is conducted in the presence of a sample body fluid and the reverse transcriptase. After the detection of the reacted or the unreacted biotinylated deoxyuridine triphosphate, the reverse-transcriptase-neutralizing and/or inhibiting antibody titer in the sample body fluid is determined.
