We will do an expression evaluation and optimization step for all protein produciton project at pilot stage. If the expression level is low, we will communicate with you if you want us to proceed to production (1-liter expression and purification and scale-up production) or not. Either way, we will only charge you the steps we performed for you. If this is a guaranteed package in E.coli expression system, we will only charge you the set up fee if we could not meet the guaranteed protein amount for you.
