ASSAYS FOR DETECTING THE TAT PROTEIN IN HIV-1 INFECTION

摘要

A method for detecting or measuring HIV-I Transactivating (Tat) protein in a biological sample comprising contacting the biological sample with an amount of a basic protein effective to reduce interference with binding between anti-HIV-1 Tat Epitope 2 ligand and Tat that is caused by acidic components within the sample or reagents. A more accurate detection and measurement of the amount of HIV-I Tat in the sample is obtained by binding between the anti-Epitope 2 antibody and the Tat in the sample when the interference is neutralized. A diagnostic kit for use in practicing the method contains these components. Preferred basic proteins are protamine sulfate, poly-Arg and poly-Lys .
