Following a BLOT

It’s the ultimate protein race!

The whole idea is to identify the proteins present in a group of cells. You put them on the start line in a track of gel, fire the power of an electrical field, and they’re off!

Southern was the fellow who invented this procedure, but what we saw today was a Western, not a Southern. And there’s the Nothern, too. But those are similar different stories…
