Formatted abstract
Cell-free protein expression is an important tool for a rapid production, engineering and labeling of recombinant proteins. However the complex protocols for preparation of eukaryotic cell-free protein expression systems result in high manufacturing costs and limit their utility. Recently we reported a novel cell-free expression system based on the lysate of a fermentable protozoan Leishmania tarentolae. Herein we describe a protocol for high throughput protein expression using Leishmania cell-free lysate. The protocol combines PCR-based synthesis and engineering of translation templates with a combined transcription-translation system. The protocol is adapted to multiwell plate format and allows translation of large protein libraries. In the presented example we translate in vitro and isolate a nearly complete complement of mammalian Rab GTPases. Further applications and developments of the system are discussed.
