A number of resequencing strategies exist for such validation experiments and several rely on multiplex PCR to capture many loci in a single PCR reaction. Shicheng Guo • 8.5k. The weaknesses of multiplex PCR for next-generation sequencing are similar to those inherent in PCR-based capture methods, namely, the region must contain unique genomic sequence and not be enriched for high GC content. Compatible primers are those with similar GC content, Tm, amplicon size, and amplicons that do not target overlapping regions. eCollection 2020. Additionally, a coverage file is provided indicating which primer(s) cover what target regions. 1. To design primers for multiplex PCR, we need to adjust the amplification conditions for each primer so that the PCR product sizes of individual target sequences are separated sufficiently. TSW and DJC designed the wet-lab experiment, analyzed the data, and wrote the manuscript. Automates designs for PCR primers with highly uniform amplification of all targets. Our approach for primer pooling differs from recommendations by Fluidigm in two ways. A total of 16,295 bp were sequenced in the original targeted regions. Optionally, isPcr may be used to provide an orthogonal validation for PCR primer uniqueness and genomic coordinates.
