Learn how to use this product The RTS Linear Template Kit Plus expedites the generation of multiple templates for parallel protein expression. The constructs are well suited for expression in insect cell-free lysates and E. coli. Due to compatible restriction sites in the adapter primers, products can be easily cloned into pIX3.0 vectors for large-scale in vitro expression. The kit contains primers providing regulatory elements required for optimal transcription and translation in cell-free expression systems. Specially designed 5'-untranslated regions reduce the formation of secondary structure in the translation initiation region, one of the most common causes of low expression rates. A Strep-tag II or His-tag can be added to either terminus, significantly simplifying protein purification and detection. A signal sequence enables the expression of functional proteins containing disulfide-bonds or membrane proteins in RTS 100 Insect Membrane or Disulfide kits. A signal peptide can be introduced using the N-terminal primer containing a melittin sequence. This enables protein translocation into microsomal vesicles derived from insect cell endoplasmic reticulum.
