| Main SKU |
Human cytomegalovirus (HCMV), also known as human betaherpesvirus 5, belongs to the herpesviruses. Gene transcription relies on the host RNA polymerase, but the virus carries its own DNA polymerase, a key enzyme of the lytic phase of infection.
Kit vs Kit Plus
The only difference is the enzyme: HCMV100K has all reagents except the HCMV DNA polymerase, while HCMV100KE also includes 33 µl of 100 x HCMV DNA polymerase. Both are for 100 assays.

Kit Components
| Component | Kit (enzyme not included), 100 assays (HCMV100K) | Kit Plus (enzyme included), 100 assays (HCMV100KE) |
|---|---|---|
| 10 x Buffer | 400 µl | 400 µl |
| 100 x DNA template | 33 µl | 33 µl |
| 100 x dNTP | 33 µl | 33 µl |
| 2 x Dye | 1550 µl | 1550 µl |
| 50 mM EDTA | 1550 µl | 1550 µl |
| 100 x HCMV DNA polymerase | Not included | 33 µl |
Assay Principle
The DNA polymerase makes new DNA from a DNA template and dNTPs. A fluorescence dye diluted in EDTA is then added, and the signal at 535 nm (excitation 485 nm) reflects the DNA made, so inhibitors lower the signal.
