Abstract:
Reverse transcriptase (RT) assay is commonly used to detect enzyme activity associated with retroviral-like particles. Previously, detection of RT activity in virus-infected cultures was done using a radioisotope-based assay system. However, assay systems, which detect the antigen directly(as opposed to antibody ELISA assays), have been developed. For diagnostic purposes, RT activity and p24 antigen capture assays are the two most commonly used methods for detection of retroviral infection. More recently, new non-radioactive assay systems have been developed. In this study, four non-radioactive reverse transcriptase kits were evaluated using samples obtained from a chimeric virus, simian/human immunodeficiency virus (SHIV) and SIV-infected cell cultures. The results showed that the magnesium kit was the most appropriate for detection of SIV and SHIV infection in cell culture supernatants.
