The Western Blot is a technique. It's the transfer of the results of an RNA electrophoresis onto a membrane. It's like a Northern Blot, but with RNA. It can be used to check for specific RNAs.
There is also something called a Northern Blot which I'm more familiar with, that involves DNA. You chop up DNA with restriction endonucleases and electrophoresis them. Then you use a Northern Blot to transfer the pattern of DNA migration onto a membrane. You visualize the bands of DNA using DNA probes with markers.
