Protein Research Kits provide premixed reagents to perform cell-free protein expression reactions starting directly from a DNA template in an easy to setup, fast two-step process. Each kit contains the reagents to perform 24 SP6-driven mRNA expression and wheat germ protein synthesis reactions. In addition, reaction tubes for the bilayer protein expression reaction are included.

Each protein expression reaction can yield some 30g of crude protein. This is sufficient for most experimental designs to analyze your proteins of interest. Special versions of the Protein Research Kit are available for the preparation of GST- and His-tagged fusion proteins. These kits contain wheat germ extracts that have been pretreated to remove proteins binding to glutathione or nickel resins respectively. Hence those wheat germ extracts allow for higher protein purity of tagged proteins after the purification step.

Expression vectors or PCR primers required for protein expression are not included in the Protein Research Kits. You can obtain those by purchasing the Premium PLUS Kit for setting up our expression system.
