Hi bionetters,

Sorry I did not get back earlier. It seems that Bob's answer summarizes the
general feedback I got about what densitometry programs are  available in
the public domain (Gel reader and Image). I heard some people formulating
reservations about Gel reader although I never used it before. Image is OK
by my standards as long as the image capture is good. Thanks to everybody
for their answers.
