The Flaviviridae are a family of enveloped, positive-sense single-stranded RNA viruses. Their RNA-dependent RNA polymerase copies the viral RNA and is used here as a target for enzyme tests and inhibitor screening.
Pack Sizes
Both sizes contain the same reagents and neither includes the enzyme. The only difference is the number of assays: VRT100K is for 100 assays and VRT500K for 500 assays (384-well format), with component volumes scaled.
| 100 assays (VRT100K) | 100 assays; enzyme not included |
|---|---|
| 500 assays (VRT500K) | 500 assays; enzyme not included |
Kit Components
| Component | 100 assays (VRT100K) | 500 assays (VRT500K) |
|---|---|---|
| 10 x Buffer | 350 µl | 1550 µl |
| 10 x MnCl2 | 350 µl | 1550 µl |
| 100 x RNA template | 33 µl | 160 µl |
| 100 x NTPs (50 mM ATP and 50 mM GTP) | 33 µl | 160 µl |
| 10 x Fluorescence dye | 330 µl | 1550 µl |
Assay Principle
The polymerase makes new RNA from an RNA template in the presence of ATP and GTP. A fluorescence dye is then added and the signal at 535 nm (excitation 485 nm) reflects the amount of RNA made, so inhibitors lower the signal.
