Have I Got Good Protein Expression News for You

Have I Got Good Protein Expression News for You

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, which are full of confusing technical details, nor the protocols, which tell you how to do something but not why, fulfill this function.

What you need is something in between, a simple and maybe even funny introduction into protein expression, how to select parts, and optimize production. The good news is that our site is launching The Manual – an 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.

Check out the e-book content:
