In Brief: An Intro to Western Blotting

You’ve heard about Western Blotting and have maybe even done it in the lab. But following a protocol doesn’t answer basic questions about the origin of Western blotting and the components and apparatus used. This article is not an in-depth description of the science. It just answers your basic questions about how and why Western blotting came to be and the equipment used to perform the technique.
