What is PCR?
Polymerase Chain Reaction (PCR) is a laboratory technique used to amplify and analyze DNA. By creating millions of copies of a specific DNA segment, PCR enables researchers and clinicians to study and manipulate genetic material more efficiently. This process is essential in fields such as molecular biology, genetics, medicine, and forensic science.

Why Use a PCR Calculator?
A PCR calculator helps you determine the optimal conditions for your PCR experiment. It takes into account various factors like reaction volume, primer concentration, DNA template, and enzyme efficiency. Whether you’re designing a new experiment or optimizing existing conditions, the PCR calculator can assist in ensuring your reaction is successful and efficient.
Key Parameters for PCR Optimization
- Template DNA Concentration – The amount of DNA you have in your sample.
- Primer Concentration – The amount of forward and reverse primers used to initiate the PCR reaction.
- DNA Polymerase Efficiency – The enzyme responsible for synthesizing new DNA strands.
- Reaction Volume – The total volume of your PCR reaction mix.
- Annealing Temperature – The temperature at which primers bind to the DNA template.
- Extension Time – The duration of DNA strand synthesis during the PCR process.
How to Use the PCR Calculator
- Enter Template DNA Concentration: Input the concentration of your DNA template in nanograms per microliter (ng/µL).
- Input Primer Concentration: Enter the concentration of your forward and reverse primers in nanomolar (nM).
- Set Reaction Volume: Enter the desired reaction volume in microliters (µL).
- Select Enzyme Efficiency: Choose the enzyme efficiency based on the enzyme you’re using.
- Set Annealing Temperature and Extension Time: Input the recommended values or adjust them based on your needs.
- Calculate: Once all parameters are entered, click the “Calculate” button to get your optimized PCR conditions.
PCR Calculation Example
If you’re conducting a standard 50 µL PCR reaction with the following parameters:
- Template DNA concentration: 20 ng/µL
- Primer concentration: 0.2 µM
- DNA polymerase efficiency: 95%
- Annealing temperature: 55°C
- Extension time: 1 minute
Our PCR calculator will determine the ideal amounts of each reagent and the most effective reaction conditions for your experiment.
