1. PCR
PCR (polymerase chain reaction) amplifies specific DNA segments so you can read, quantify, or manipulate them. A small signal becomes something you can measure.
Why It's Important
It underpins genotyping, cloning, pathogen detection, and expression analysis. Fast, sensitive, and incredibly versatile.
How to Improve PCR Skills
- Primer design: Check specificity, melting temperatures, GC content, and avoid strong secondary structures. Test two or three primer pairs when a locus is tricky.
- Annealing temperature: Run a gradient to find the sweet spot that trims nonspecific bands without killing yield.
- Mg2+ and additives: Titrate magnesium; for GC-heavy targets, try DMSO or betaine to loosen stubborn structures.
- Polymerase choice: Use high-fidelity enzymes for cloning or variant calling; standard Taq for routine checks.
- Template quality and input: Clean prep, no inhibitors. Typical loads: 1–10 ng plasmid DNA; ~10–100 ng genomic DNA.
- Hot-start setups: Reduce spurious amplification by activating the enzyme at higher temperature.
- Cycle number: More isn’t better. Stop as soon as you have enough product to curb errors and smears.
- Controls and contamination guardrails: Include no-template controls, segregate pre- and post-PCR areas, use filtered tips. For RT-PCR, treat with DNase and verify minus-RT controls.
