Systematic Cross-Primer Compatibility Analysis
The core challenge of multiplex PCR is ensuring that all primers coexist without interfering. VigyanLLM performs pairwise cross-dimer analysis across all primer combinations (not just within pairs, but between every forward and every reverse primer), evaluates GC content distribution, and ensures amplicon sizes are sufficiently different for clear separation on gels or distinct identification on capillary electrophoresis systems.
Multiplex Scoring and Ranking
VigyanLLM generates a multiplex compatibility score for each panel design, considering dimer risk, Tm uniformity, amplicon size distribution, and GC balance. Multiple panel candidates are ranked by overall score, allowing you to select the optimal combination. The detailed report shows which pairs have the lowest cross-interaction risk and which might need adjustment.
Frequently Asked Questions: multiplex PCR primer design
How do I design primers for multiplex PCR?
Multiplex PCR requires all primer pairs to amplify efficiently in the same reaction tube. This means all primers must have similar melting temperatures (within 2°C), produce amplicons of distinguishable sizes, and have minimal cross-primer interactions. VigyanLLM designs multiplex panels by first selecting optimal primer pairs for each target individually, then evaluating all possible cross-primer combinations for dimers and competition, and finally selecting the best-performing set.
How many targets can VigyanLLM multiplex?
VigyanLLM's multiplex scoring engine evaluates panels with up to 20+ primer pairs. The platform scores each primer pair for individual performance and evaluates the complete panel for cross-interactions, Tm uniformity, amplicon size separation, and overall amplification balance. The practical limit depends on your target regions and platform capabilities, but VigyanLLM's systematic approach maximizes multiplex capacity.
