Define the target and primers
Record the target accession or genomic region, expected amplicon size, and a validated target-specific primer pair. This starter intentionally supplies no primer sequence.
Create the tube map and controls
Assign samples and controls before opening reagents so that every result can be interpreted against contamination and amplification controls.
Prepare the master mix
Prepare enough primer-containing master mix for all reactions plus pipetting overage. Add template separately.
Aliquot and add template
Dispense master mix, add the planned template volume to each sample, replace template with nuclease-free water in the NTC, then cap and briefly spin.
Initial denaturation
Denature the input template using the starting condition for a routine Taq reaction.
Cycle — denaturation
Denature amplified DNA at the start of each cycle.
Cycle — primer annealing
Anneal the validated primer pair. Optimize with a gradient when the assay is new or specificity is poor.
Cycle — extension
Extend the amplicon using the temperature and rate required by the selected polymerase.
Final extension and hold
Complete partially extended products, then hold the reactions until collection.
Verify the endpoint product
Resolve an appropriate aliquot with a size standard and confirm a product at the expected size. Interpret samples only when controls behave as planned.
