Hi all!

When someone cites a sensitivity limit of a certain amount (i.e.
picograms) per square mm cross band width, what are they talking
about?  I'm not sure what the term "cross band width" applies to.

Also, could someone please rate for me the following DNA/RNA detection
methods in terms of sensitivity?  1. silver stain 2. dye stain 3.
autoradiography 4. UV detection 5. any others that might work...

Thanks in advance for advice on either of my questions!

Sincere regards,
JJ Miranda
