Abstract

The program "molecular weights" allows a fast and easy estimation of molecular weights (M(r)), isoelectric point (pI) values and band intensities directly from scanned, polyacrylamide gels, two-dimensional protein patterns and DNA gel images. The image coordinates of M(r) and pI reference standards enable the program to calculate M(r) and pI values in a real time manner for any cursor position. The program requires NIH-Image for Macintosh computers and includes automatic band detection coupled with a densitometric evaluation.
