How It Works
This calculator uses semi-logarithmic regression to estimate DNA fragment sizes. In gel electrophoresis, DNA migration distance is inversely proportional to the log10 of fragment size. Enter known standards (ladder bands) and their migration distances, then input your unknown band distance to calculate its estimated size. A higher R-squared value (closer to 1.0) indicates better fit and more reliable estimates.
About Gel Electrophoresis
Gel electrophoresis is a laboratory method used to separate mixtures of DNA, RNA, or proteins according to molecular size. This calculator helps estimate DNA fragment sizes based on their migration distance in agarose or polyacrylamide gels.
