Assay Analyser
Analyse plate reader measurements or from on-chip microfluidic measurements, ELISAs and other quantitative assays. Upload your Excel file, fit a 4-parameter logistic (4PL) calibration curve, and interpolate unknown sample concentrations — with built-in QC validation and replicate statistics. Ideal for processing absorbance, fluorescence or luminescence data collected from microfluidic chips and 96 well plates.

How to Use
Data Format
Your Excel file needs 3 columns(or 4 for triplicates). One row per calibrator or sample. The tool auto-detects calibrators vs samples from column A:
| Column | Calibrator Rows | Sample Rows |
|---|---|---|
| A | Known concentration (e.g. 125) | Sample name (e.g. "Patient 03") |
| B | Replicate reading 1 | Replicate reading 1 |
| C | Replicate reading 2 | Replicate reading 2 |
| D (optional) | Replicate reading 3 | Replicate reading 3 |
Example Layout
| Column A | Rep 1 | Rep 2 |
|---|---|---|
| 0 | 0.048 | 0.052 |
| 3.9 | 0.090 | 0.056 |
| 15.6 | 0.261 | 0.248 |
| 125 | 1.327 | 1.299 |
| 1000 | 2.583 | 2.536 |
| Patient 01 | 0.149 | 0.143 |
| Patient 02 | 0.352 | 0.344 |
Import Steps
- 1. Click Import Data in the sidebar
- 2. Drop your
.xlsxfile or click Browse - 3. Auto-detection scans column A — numbers are calibrators, text entries are samples, empty rows are skipped
- 4. Review detected rows and adjust if needed
- 5. Click Analyze to review the 4PL fit
- 6. Click Load Dashboard — done
Tips
- Blank calibrators: use 0 in column A (not empty)
- A header row with text in all columns is auto-skipped
- Separate calibrators from samples with one empty row (optional but recommended)
- Supported formats:
.xlsx.xls.csv - The tool fits a 4-parameter logistic (4PL) curve and computes R², residuals, and interpolated concentrations
- CV% is calculated for any group with 2+ readings — singlets show "n=1"
Beta — results should be independently verified. Not for clinical or diagnostic use.
