Which plug-in or what function of image J do people use to quantify their bands from in western blots?

I've been using the "Analyze/Gel" function, but not sure that is actually the correct way to go.

Suggestions?

you use a mac or pc?

I use PC

I found out the best way is to use the Ctrl +M "Measure function" for each band and in the measurement options select "Integrated Density"

This has worked very well since I implemented it.

Any one got an old version for an old PC.
The one that I downloaded from the site needs a Mac OSX I got Mac OS IX

(no experience with that I must admit)

for the Ctrl + M, you will need first do the color invert
