Tools like or custom amplicon pipelines often wrap Primer3. They generate thousands of potential tiles across a genome, feed them to primer3_core , and filter the output to create multiplexed panels. primer3 0.4.0

If your bands are faint, try adding a GC enhancer to your reaction mix or slightly increasing the primer concentration (standard is often around 0.15–0.2 µM ). Pro-Tip: Beyond the Defaults , a cornerstone tool in bioinformatics that revolutionized
