Learn how to use this product The biotechrabbit™ RTS 100 Insect Membrane Kit can be used with linear templates and expression vectors, and it was the first commercially available in vitro protein synthesis kit based on cell lysates derived exclusively from insect cell cultures. These homogeneous lysates from a Spodoptera frugiperda cell line enable efficient expression of a broad range of eukaryotic proteins with post-translational modifications. This kit is even more efficient with an optimized lysate production procedure. In addition, the lysates contain functional organelle membrane fractions, whose activity is required for post-translational modification of eukaryotic proteins, including membrane proteins.
