Rapid expression of functional protein

Invitrogen’s mammalian protein expression services utilize serum-free FreeStyle™ 293 and CHO-S cell lines to transiently express your protein.

Overview
Producing a functional mammalian protein often necessitates using a mammalian host to ensure proper posttranslational modification and function. Protein expression in Invitrogen’s proprietary serum-free FreeStyle™ 293 and CHO-S suspension systems allows for rapid production of functional, soluble proteins. www.invitrogen.com/freestyle

Small-scale expression studies
Multiple expression time points can be evaluated in FreeStyle™ 293 and CHO-S cell lines simultaneously, to quickly optimize your service expression conditions.

Expression scale-up
From 1 L to 200 L

Protein purification services
Affinity, ion exchange, HIC, SEC, and other purification methods are employed.
