Cell-free Expression Systems

Daicel Arbor Biosciences provides flexible solutions for protein engineering and synthetic biology applications


The myTXTL Cell-free Expression System includes kits for protein synthesis, enzyme engineering and synthetic biology in industrial and academic applications:

myTXTL Sigma 70 Master Mix Kit is a rapid, easy-to-use cell-free master mix for protein expression in vitro, based on E. coli σ70 gene expression. The myTXTL Linear DNA Expression Kit was optimized for cell-free protein synthesis from linear DNA template molecules and the myTXTL T7 Expression Kit  has been designed for maximum robustness and reliable performance when using T7 promoter-driven constructs.

For setting up complex gene circuits a large collection of over one hundred pre-designed expression vectors can be offered for your convenience.
