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 115-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 28-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 3Comparison 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).
