Assay & Quantification Tools
Fit calibration and dose-response curves, convert enzyme activity units, and work out qPCR efficiency, DNA copy number or protein concentration.
Dose-Response Curve Fit (IC50)
Fit a 4-parameter logistic curve to dose-response data and solve IC50 or EC50.
Open tool →qPCR Standard Curve Calculator
Fit a qPCR standard curve from your Cq values and read off amplification efficiency, slope, R² and ΔCq — then back-calculate an unknown sample's template quantity.
Open tool →DNA Copy Number Calculator
Convert DNA mass to molecule copy number (and back) from template length, with a quick-reference table for amplicons, plasmids, E. coli and human genome templates.
Open tool →Protein Assay Calculator (BCA/Bradford)
Build a BCA or Bradford standard curve, interpolate sample absorbance to protein concentration, and correct for the dilution factor.
Open tool →Enzyme Activity Unit Converter
Convert between U, mU, nkat, µkat and katal, or compute activity from an absorbance rate using extinction coefficient, path length and protein concentration.
