1. What is the Bioline Equation?

The Bioline equation calculates PCR yield based on efficiency and number of cycles. It helps estimate the amplification factor in polymerase chain reactions.

2. How Does the Calculator Work?

The calculator uses the Bioline equation:

Where:

• \( PCR\ Efficiency \) — Efficiency of the PCR reaction (0-1)
• \( Cycles \) — Number of amplification cycles

Explanation: The equation shows exponential growth of DNA fragments with each cycle based on the reaction efficiency.

3. Importance of Yield Calculation

Details: Accurate yield estimation helps in experimental planning, determining optimal cycle numbers, and ensuring sufficient product for downstream applications.

4. Using the Calculator

Tips: Enter PCR efficiency as a decimal (e.g., 0.95 for 95% efficiency) and the number of cycles. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is typical PCR efficiency?
A: Most well-optimized PCR reactions have efficiencies between 0.9-1.0 (90-100%).

Q2: How does efficiency affect yield?
A: Small differences in efficiency lead to large differences in yield over many cycles. 95% vs 90% efficiency yields 12.6x vs 31.4x after 30 cycles.

Q3: What is the maximum theoretical yield?
A: With 100% efficiency, yield = 2^cycles (e.g., 1.07 billion-fold after 30 cycles).

Q4: Why might actual yields differ?
A: Reaction inhibition, reagent limitations, or plateau effects can reduce actual yields below theoretical calculations.

Q5: How can I improve PCR efficiency?
A: Optimize primer design, annealing temperature, Mg2+ concentration, and template quality.
