Electrophoresis Band BP Calculator
Estimate DNA Size from Gel Image — Mobile Friendly

What is the Electrophoresis Band BP Calculator?

The Electrophoresis Band BP Calculator is a web-based tool designed to help researchers, students, and lab technicians estimate the size of DNA fragments in base pairs (bp) from gel electrophoresis images. By marking known ladder bands and inputting their bp values, the tool generates a semi-log calibration curve. Unknown bands can then be analyzed and automatically converted to estimated bp values. This makes it ideal for quick, accurate, and visual interpretation of agarose or polyacrylamide gel results in molecular biology, biotechnology, and genetic analysis.
