Protein Expression

Express Protein in Hours, Not Days!

Choose from an extensive range of eukaryotic cell-free protein expression systems. Kits optimized for in vitro transcription and translation of plasmid DNA, RNA or PCR DNA are available.

Protein Expression and Mass Spectrometry Categories

Eukaryotic Cell-Free Protein Expression Use plasmid or PCR DNA as templates to express full-length, soluble, functional protein in 1-4 hours with the TnT® cell-free systems. No requirement to reclone; use standard vectors containing either a T7, T3 or SP6 promoter.

Prokaryotic Cell-Free Protein Expression Express up to 500µg/ml protein directly from circular plasmid DNA using a cell-free E.coli-based system. No requirement for special equipment. Kits also available for linear or PCR DNA templates.

Proteases and Surfactants Proteases for optimal digestion of proteins in mass spectrometry and other applications. Includes Chymotrypsin, rLys-C, Lys-C, Asp-N, Glu-C and others. ProteaseMAX™ Snurfactant is available for improved in-gel digestion and protein solubilization.

Glycosidases Utilize PNGase F and Endo H to characterize protein glycosylation. Typical applications include monitoring protein trafficking or determining location and structure of glycans by mass spectrometry.

Mass Spectrometry Reference Reagents Mass spectrometry-compatible yeast and human protein extracts designed for use in instrument monitoring. The extracts are predigested and cleaned up by solid-phase extraction ready for immediate use in liquid chromatography/mass spectrometry (LC/MS) analysis.

Cell-Based Protein Expression Convenient mammalian systems and competent cells designed for easy, controlled protein expression.

Analysis of Translational Regulation Rabbit Reticulocyte Lysate Translation Systems for the identification of mRNA species, characterization of their protein products and the investigation of viral replication and translational control.

Protein Labeling and Detection Cell imaging, in vivo imaging and protein localization systems. Fluorescent and colorimetric labeling systems for immunoblotting.

Protein Deamidation Detection The ISOQUANT® Isoaspartate Detection Kit offers a safer alternative to radioactive methods for protein deamidation testing.
