SIZE: a program to determine the size of nucleic acid and protein molecules from gel mobilities

The relationship between fragment length and the reciprocal of mobility and the least-squares curve fitting analysis for this relationship have been combined into a user-friendly program for determining the size of unknown DNA fragments by reference to known standards. Protein sizes can be determined in the same way. The program offers an accurate, simple-to-use mechanism for sizing molecules that requires only an IBM-compatible computer.
