Take control with more kit options that meet your exact needs
 

Diagram of tailored PURExpress® Kits for cell-free protein expressionNEB® now offers a new suite of customized PURExpress® in vitro protein synthesis kits through our Customized Solutions channel. Designed for researchers seeking greater control over cell-free protein synthesis (CFPS), these pre-configured kits feature specific components of the PURExpress system selectively omitted, giving you the freedom to experiment with your own additions or modifications. Each kit is built to order with a defined configuration, making it easier to select the right solution for your needs without starting from scratch.

Interested in a PURExpress Master Mix containing everything you need in 1 tube? We can do that too. This formulation is perfect for enabling automated workflows and can be ordered with or without Disulfide Bond Enhancer or Murine RNase Inhibitor.
 
These kits and master mixes are ready-to-order through our Customized Solutions Team.
 
Note: a minimum order quantity may be required, and lead times will vary.
