[A nonisotopic method of quantitative PCR analysis in diagnosing HIV infection].

A nonisotopic method for the detection of HIV DNA has been developed, based on the use of avidin-biotin complex to identify the products of polymerase chain reaction (PCR). Biotin label integrated in deoxyuridine triphosphate (bio-11-dUTP) was incorporated in the structure of amplified fragments in the course of PCR. The resultant products were identified in hybridization reaction with specific HIV DNA adsorbed on polystyrene plates.

[Primers for the nef gene in the diagnosis of HIV infection using the polymerase chain reaction].

A new system of primers and internal probe identifying the nef gene of HIV-1 was selected and tested for the laboratory diagnosis of HIV infection by means of PCR. The proposed primers and probe by their characteristics approached the optimal ones for PCR diagnosis. The diagnostic value of the above system was confirmed by the PCR analysis of blood samples from 29 patients including subjects with a doubtful diagnosis of HIV infection.
