Quantification of electrophoresis gel bands using QuPath and Galaxy imaging tools

Abstract

Electrophoresis gel images are fundamental tools in molecular biology and biochemistry for separating DNA, RNA, or protein fragments by size or charge. Quantification of these bands allow for estimating product yield, comparing amplification efficiency, verifying PCR products, calculating molecular weights, and assessing enzyme activity or protein purity.

About This Material

This is a Hands-on Tutorial from the GTN which is usable either for individual self-study, or as a teaching material in a classroom.
