The Flexi® Vector System is a simple, yet powerful, directional cloning method for protein-coding sequences. It is based on two rare-cutting restriction enzymes, SgfI and PmeI, and provides a rapid, efficient and high-fidelity way to transfer protein-coding regions between a variety of Flexi® Vectors without the need to resequence.
The vectors below are designed with special sequences for maximal cell-free protein expression in a specific system. The pF3A/K WG vectors were designed for use with Wheat Germ extracts and contain sequences from the barley yellow dwarf virus (BYDV), an RNA plant virus, upstream and downstream of the protein coding region of interest. The BYDV elements interact with each other, form a closed loop and act synergistically to stimulate translation in wheat germ extracts, bypassing mRNA cap and polyadenylation dependencies. The pF25A/K ICE Vectors were designed for use with Insect Cell Extracts and contain untranslated region (UTR) sequences at the 5´ and 3´ ends of the gene coding region to enhance translation efficiency.
Note:Flexi® Vectors contain the lethal barnase gene to reduce background colonies without inserts during the subcloning procedure. Using the Flexi® Vector Cloning System replaces the barnase gene with your insert. These vectors, as purchased, cannot be cultured in normal laboratory strains ofE. coliwithout an insert.
Features - Benefits
Versatility:You can choose between a variety of initial applications (e.g., bacterial protein, mammalian, or cell-free protein expression) and then transfer to others as required.
Time Savings:Efficient transfer allows for direct use of recombinant clones, minimizing time wasted screening background colonies.
Enhanced Productivity:Adaptable to high-throughput formats for large screening projects.
Easy Access:No licensing fees or complicated transfer restrictions.
Applications
Clone ORF and conveniently transfer these inserts to a variety of vectors designed for multiple applications.
