Calculate protein molecular weights, generate standard curves, detect bands automatically, and export publication-ready results directly from your device.
SDS-PAGE Gel Analyzer is a powerful scientific tool designed for researchers, students, educators, and laboratory professionals who need to determine protein molecular weights from polyacrylamide gel electrophoresis images quickly and accurately.
The application simplifies gel analysis by allowing users to upload gel images, mark protein standards and unknown bands, generate semi-log regression curves, and calculate molecular weights in real time. Advanced image enhancement tools, automatic band detection, multiple sample lane support, and publication-ready exports make the workflow efficient and reliable.
Whether you are conducting protein characterization, teaching electrophoresis techniques, or preparing publication-quality figures, SDS-PAGE Gel Analyzer provides the tools you need in a modern and intuitive interface.

SCIENTIFIC ANALYSIS
The analyzer uses the established SDS-PAGE relationship between protein migration distance and molecular weight. A semi-logarithmic regression curve is generated using known protein standards:
Unknown protein molecular weights are calculated automatically using the fitted regression equation. The application also reports the coefficient of determination (R²) to help evaluate standard curve quality and analysis reliability.
