Introduction

Calculating PCR amplification is crucial in molecular biology research, aiding in determining the number of copies of a target DNA sequence after a specific number of amplification cycles. A PCR amplification calculator simplifies this process, providing accurate results efficiently.

How to Use

Using the PCR amplification calculator is straightforward. Input the initial amount of DNA, the amplification efficiency (as a percentage), and the number of amplification cycles. Click the “Calculate” button to obtain the result, which represents the final amount of DNA after amplification.

Formula

The formula used for PCR amplification calculation is:

Final DNA amount = Initial DNA amount * (1 + (Efficiency / 100))^Cycles

Where:

• Final DNA amount is the resulting amount of DNA after amplification.
• Initial DNA amount is the starting quantity of DNA.
• Efficiency is the amplification efficiency, expressed as a percentage.
• Cycles is the number of amplification cycles.

Example Solve

Let’s consider an example:

• Initial DNA amount: 1000 molecules
• Efficiency: 90%
• Number of cycles: 30

Using the formula: Final DNA amount = 1000 * (1 + (90 / 100))^30

After calculation, the final DNA amount is approximately 3,366,495 molecules.
