Human mitochondrial RNA polymerase (h-mtRNAP or POLRMT) acts as the transcriptase for gene expression and as the primase for replication of mitochondrial DNA. Its malfunction is linked to various diseases and to aging.
Some antiviral nucleoside analogs have been reported to cause chronic toxicity related to inhibition of mitochondrial RNA polymerase.
Kit vs Kit Plus
The only difference is the enzyme: MRPA100KE includes 33 µl of 100 x human mitochondrial RNA polymerase, while MRPA100K has the same buffer, DNA template, NTP mix and dye without it.

Kit Components
| Component | Kit (enzyme not included) (MRPA100K) | Kit Plus (enzyme included) (MRPA100KE) |
|---|---|---|
| 10 x Buffer | 400 µl | 400 µl |
| 100 x DNA template | 33 µl | 33 µl |
| 100 x NTP mix | 33 µl | 33 µl |
| 10 x Fluorescence dye | 330 µl | 330 µl |
| 100 x human mitochondrial RNA polymerase | Not included | 33 µl |
Assay Principle
The assay measures the RNA made by the polymerase from a DNA template and NTPs. After the reaction a fluorescence dye is added and the signal is read at 535 nm with excitation at 485 nm.
