How to Use the qPCR Efficiency Calculator
Calculate quantitative real-time PCR assay efficiency:
Run Serial Dilution
Run a 10-fold serial dilution qPCR standard curve.
Enter Slope
Input Ct vs. log dilution slope from qPCR software.
Calculate Efficiency
Engine applies Efficiency = (10^(-1/slope) - 1) × 100%.
Verify MIQE Standards
Check if efficiency falls within MIQE guidelines (90-110%).
Key Features & Real-Time PCR Analytics
MIQE Compliance Verification
Validates qPCR primers according to MIQE publication standards.
Amplification Factor per Cycle
Calculates exact product doubling factor per cycle (ideal 2.0x).
100% Private Client Compute
Runs in browser memory with zero tracking or server logs.
qPCR Assay Guide: Standard Curves & Amplification Efficiency
In real-time quantitative PCR, 100% efficiency means that every target template molecule doubles during each thermal cycle. A slope of -3.322 represents 100% efficiency. Slopes flatter than -3.1 indicate PCR inhibition or non-specific amplification, while slopes steeper than -3.6 indicate poor primer binding.
Frequently Asked Questions
?What is the ideal slope for a qPCR standard curve?
