Descrizione generale
Colorimetric enzyme immunoassay for the quantitative determination of retroviral reverse transcriptase activity by incorporation of digoxigenin- and biotin-labeled dUTP into DNA.
Applicazioni
The Reverse Transcriptase Assay is designed for the quantitative determination of RT activity in cell culture and other biological samples. The assay is used to determine the propagation of retroviruses in retrovirus-infected mammalian cells in culture. The assay is also used for in vitro screening for RT inhibitors.
Confezionamento
1 kit containing 14 components.
Specifiche
Assays for reverse transcriptase (RT) activity have been broadly applied for testing retroviral propagation in vitro. RT is required for early proviral DNA synthesis, and is thus a prime target for anti-retroviral therapy, for example, in the case of acquired immunodeficiency syndrome (AIDS). Reverse transcriptase generally uses RNA, which is complexed with various primers, as a template for DNA synthesis. Classically, for the detection or quantification of RT activity, the amount of incorporated radioactively labeled nucleotides is measured.
Assay time: Approximately 4 hours (for an enzyme reaction of 1 hour), approximately 18 hours (for an enzyme reaction of 15 hours).
Sample material: Cell culture supernatant and other biological samples, RT inhibitors.
Sensitivity: The Reverse Transcriptase Assay detects 20pg HIV-1 reverse transcriptase in a 1-hour reaction. One pg can be detected in an overnight reaction.

Sensitivity: The Reverse Transcriptase Assay detects 20pg HIV-1 reverse transcriptase in a 1-hour reaction. One pg can be detected in an overnight reaction.
The assay detects the activity of natural or recombinant retroviral reverse transcriptase, including that of HIV-1, HIV-2, SIV-1, AMV, and M-MulV.
Principio
The Reverse Transcriptase Assay, colorimetric, takes advantage of the ability of reverse transcriptase to synthesize DNA using the hybrid poly (A) x oligo (dT)15 as a template and primer. It avoids the use of [3H]- or [32P]-labeled nucleotides that are employed in standard RT assays. In place of radiolabeled nucleotides, digoxigenin- and biotin-labeled nucleotides in an optimized ratio are incorporated into the same DNA molecule by the RT activity. A template/primer hybrid is supplied, but the flexibility of the assay allows the use of a template of choice (e.g., a viral template). The detection and quantification of the synthesized DNA as a parameter for RT activity follows a sandwich ELISA protocol: biotin-labeled DNA binds to the surface of streptavidin-coated microplate modules. In the next step, an antibody to digoxigenin, conjugated to peroxidase (anti-DIG- POD), is added and bound to the digoxigenin-labeled nucleotides (Licensed by Institute Pasteur). In the final step, the peroxidase substrate ABTS is added. The peroxidase enzyme catalyzes the cleavage of the substrate to produce a colored reaction product. The absorbance of the samples is determined using a microplate (ELISA) reader, and is directly correlated to the level of RT activity in the sample.

HIV-1 integrase (IN) is the target for two classes of antiretrovirals: i) the integrase strand-transfer inhibitors (INSTIs) and ii) the non-catalytic site integrase inhibitors (NCINIs). NCINIs bind at the IN dimer interface and are thought to interfere primarily with viral
