PROTential™ Protein Expression Evaluation & Optimization Services

Protein Expression Services quotation

Small-scale protein expression testing is an essential, predictive step in any protein production campaign. It enables the identification of clone(s) and condition(s) that would produce recombinant soluble protein. In this regard, PROTential™ is a novel, protein expression evaluation service that allows GenScript's existing gene synthesis customers to test expression conditions of their gene(s) in the expression system(s) of their choice. In addition to our high quality, low cost, standard evaluation package, we also offer protein expression optimization packages (Silver & Gold packages) that can boost your target protein expression over 10 folds.

Purified protein won't be delivered in PROTential™ packages.

For all PROTential™ packages with bacterial expression system, a 1L expression with 1-step purification can be an add-on for just $600 more [except Flag-tagged proteins which cost $800 more for 1L expression and purification step.



Stuck with a dead-end construct that yields little or no soluble protein? Don't get frustrated, get PROTential™.
