You designed a killer protein, or you want to study a cellular pathway with precision. You also have an epic application in mind for your work. But how do you get from Point A (design/concept) to Point B (application)?

In the protein world, that's protein expression and purification - turning those valuable protein sequences into tangible, testable protein. Expressing a protein in an incompatible expression host, using default buffers or a standard purification strategy without considering your protein's specific properties and downstream requirements is a roadmap for disaster (and potentially a terminated project).

We put together a decision cheat sheet for selection of an expression host, the first step in protein production, and included a framework for collecting the key pieces of information that will help you select the right expression system for your project.
