 Description: 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 reaction using human genomic DNA (Figure 1) and an 8-plex PCR reaction using cDNA products as templates (Figure 2). The 5X formulation allows maximal input of customer 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.




 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.




 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 2-Log DNA Ladder (NEB #N3200).

Notes

 General notes:- Keep at -20°C for long term storage.
- Multiplex PCR 5X Master Mix is stable at 4°C for six months or after fifteen freeze-thaw cycles.
- For daily use, we recommend keeping an aliquot at 4°C.
Usage 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.
- Test multiplex PCR with equal molar concentration of all primer pairs, preferentially in a temperature-gradient PCR machine.
