Scientific Principles Behind the Calculator

The calculator is built on the ΔΔCt method, a peer-reviewed approach used in qPCR to quantify relative gene expression. The method involves the following steps:

• ΔCt Calculation: Subtract the Ct (cycle threshold) value of the reference gene from the target gene’s Ct value for both experimental and control samples.
• ΔΔCt Calculation: Subtract the control sample’s ΔCt from the experimental sample’s ΔCt.
• Fold Change: Calculate the relative expression using the formula 2^(-ΔΔCt), adjusted for PCR efficiency if provided.

This methodology, supported by extensive scientific literature, ensures that results are robust and reproducible. The calculator allows users to input an optional PCR efficiency value, accommodating variations in amplification efficiency for greater accuracy.

User Guidelines

To use the Relative Quantification Calculator effectively, follow these steps:

1. Input Ct Values: Enter the Ct values for the target and reference genes for both the experimental and control samples. Ensure values are accurate, typically obtained from qPCR experiments.
2. PCR Efficiency (Optional): Input the PCR efficiency (e.g., 2 for 100% efficiency) or leave it at the default value of 2.
3. Calculate: Click the “Calculate” button to obtain the relative gene expression level, displayed as a fold change.
4. Interpret Results: The result represents the fold change in gene expression relative to the control sample. A value greater than 1 indicates upregulation, while a value less than 1 indicates downregulation.

Ensure all inputs are numerical and positive to avoid errors. For detailed qPCR protocols, refer to Relative Quantification.
