TaqPath™ 1-Step Multiplex Master Mix is a single-tube, 4X RT-qPCR master mix that provides for sensitive, reproducible detection of up to four different RNA (or DNA) targets in a single multiplex reaction. Particularly useful for RNA virus detection and high throughput gene expression workflows, the mix includes thermostable MMLV reverse transcriptase, dNTPs, UNG, MUSTANG PURPLE™ dye (passive reference), and thermostable Fast DNA polymerase, all in a single tube.
This single-tube, 4X format facilitates easy reaction set up—just add user-supplied assay and sample. With reproducible performance even in the presence of inhibitors, coupled with stringent quality control to minimize lot-to-lot variation, TaqPath 1-Step Multiplex Master Mix, is a superior choice for your multiplex diagnostic testing or development needs.
Features of the TaqPath 1-Step Multiplex Master Mix include:
- High sensitivity to detect low-copy targets with reproducible CT results
- Broad dynamic range with both RNA and DNA targets
- Optimized for multiplexing up to 4 targets simultaneously with MUSTANG PURPLE reference dye
- Tolerant of inhibitors commonly found in clinical samples
