Multiplex with flexibility and minimal optimization
Simultaneously detect two or more products in a single reaction
Enhanced buffer formulation for optimal performance
5X master mix format for easy reaction setup - just add template DNA and primers
Product Information
Multiplex PCR can simultaneously detect two or more products in a single reaction. There is an increasing demand for multiplex PCR techniques in assays conducted in research laboratories and forensic/diagnostic genotyping assays (1,2). Multiplex PCR can also be used for semi-quantitative gene expression analysis using cDNA templates.
The NEB Multiplex PCR 5X Master Mix is an easy-to-use solution featuring high quality recombinant Taq DNA Polymerase. The mix is optimized for high yield and robust performance. Its performance is illustrated in a 15-plex PCR using human genomic DNA (Figure 1) and an 8-plex PCR using cDNA products as templates (Figure 2). The 5X formulation allows the user maximal input of primers, template DNAs and additional components.
Figure 1 15-plex PCR using varying amounts of human genomic DNA. 1X Multiplex PCR 5X Master Mix was used with 0.15 μM of each primer. The cycling conditions were 95°C for 1 minute, 35 cycles of 95°C for 20 seconds, 60°C for 1 minute and 68°C for 2 minutes. Marker M is the 1 kb Plus DNA Ladder (NEB #N3200).Figure 2 8-plex PCR using cDNA products from 1 ng human spleen total RNA. Cycling conditions were 95°C for 1 minute, 30 cycles of 95°C for 20 seconds, 60°C for 30 seconds and 68°C for 2 minutes. Amplicon lengths are indicated next to gel.Figure 3 Comparison of PCR product yields between single-plex and multiplex PCR reactions. Figure A shows amplification of human genomic DNA fragments (sizes are listed to the left of the gel). Lane 1 is a 3-plex reaction, Lanes 2-4 are single-plex reactions, and Lanes 5–6 are 2-plex reactions; Lane 7 is the 1 kb DNA Ladder (NEB #N3232 ). Figure B shows the results of expression analysis of five mRNAs using cDNA templates (first strand synthesis was carried out using the ProtoScript Kit with human spleen total RNA); Lane 1 is a 5-plex PCR from cDNA reactions, while Lanes 2–6 are single-plex PCR reactions; Lane 7 is the 100 bp DNA Ladder (NEB #N3231).

Features
Multiplex with Taq
Product Notes
Use high quality primers (desalted or HPLC purified).
Accurately quantify and adjust primer concentrations to 50 μM in 0.5X TE Buffer.
Individually test the PCR primer pairs, preferentially in a temperature-gradient PCR machine.
Mix all primers equally at 1 μM in 0.5X TE buffer.
Keep at -20°C for long term storage.
Multiplex PCR 5X Master Mix is stable for 15 freeze-thaw cycles when stored at -20°C.
Multiplex PCR 5X Master Mix is stable at 4°C for three months. So, for frequent use, an aliquot may be kept at 4°C.

Test each primer set individually before combining into a multiplex reaction. The concentration of some primer pairs may need to be adjusted to achieve consistent and robust amplification across all amplicons in the mix.
