While the art of reading hand poured sequencing gels is forgotten as the next generation sequencers spit out genome after genome, protein expression still often requires sweat, tears and a lot of luck. I think this happens not because there is something different about protein expression in comparison with sequencing, but because people do not think about protein expression as an engineering challenge.
But where there is engineering, there should be a manual, right? Neither the literature reviews full of confusing technical details, nor protocols, which tell you how to do something but not why.
What you need is something in between, a simple and may be even funny introduction into protein expression, how to select parts and optimise production. The good news is that our site is launching The Manual – a eBook called “The Bitesize Bio Guide to Protein Expression”. Written by a team of hands-on molecular biologists: an experienced postdoc and prolific BsB writer (me) and edited by an excellent scientific editor Emily Crow.
