NEBExpress® Cell-free E. coli Protein Synthesis System
The NEBExpress® Cell-free E. coli Protein Synthesis System is an extract-based transcription/translation system derived from E. coli cells that have been engineered for high in vitro synthesis performance. It is designed to synthesize proteins ranging in size from 17-230 kDa in just 2-4 hours under the control of T7 RNA Polymerase.
- Synthesize high yields of protein (typically 0.5 mg/ml)
- Protein can be synthesized and visualized in approximately 2 - 4 hours
- Synthesize various target proteins ranging from 17 to 230 kDa
- Templates can be plasmid DNA, linear DNA or mRNA
- Minimal protease activity ensures stability of desired target protein
- RNase contamination can be inhibited by the supplied RNase inhibitor, eliminating clean-up steps
- Protein can be isolated with affinity purification or subject to direct functional analysis
- Reactions can be directly loaded onto an SDS-PAGE gel without the need for acetone or TCA precipitation
- Flexible reaction conditions achieve maximum yield; protein synthesis can be sustained for 10 hours at 37°C or up to 24 hours at lower temperatures
- Reactions can be miniaturized or scaled up
- Compatible with the PURExpress Disulfide Bond Enhancer (NEB #E6820) and NEBExpress GamS Nuclease Inhibitor (NEB #P0774)
