Build Your Own Assay Tools
Complete Set of Tools to Build Your Own Stable Cell lines and Cell-Based Assays
Take advantage of DiscoverX’s robust proprietary Enzyme Fragment Complementation (EFC) technology to develop your own stable cell lines and cell-based assays to study protein-protein interactions, compound-target engagement, cytotoxicity, protein translocation, and much more. Design your own workflows and utilize engineered parental cell lines, retroparticles, and plasmid vectors to introduce your own target of interest and create cell-based assays for multiple applications.
- Any Cell Background – Make your own stable β-arrestin recruitment or cytotoxicity cell-based assays in any dividing cell type with PathHunter® or KILR® retroparticles
- Simple Protocols – Detailed, step-by-step instructions with flow-charts and graphics to simplify assay development
- Complete Kit – Ready-to-use target engagement kit includes all the reagents you need to get you started
- Flexible Solutions – Utilize any of our cell-line expression vectors to introduce mutants, make modifications, or study unique orthologs or isotypes
Easy-to-Follow Protocols for Cell-based Assay Generation Using PathHunter® Parental Cell Lines and Plasmids
Workflow protocol schematic to show how to generate an EFC cell-based assay. Start with an engineered PathHunter® parental cell line containing EA to study subcellular translocation (e.g. including membrane receptor trafficking), SH2 recruitment for receptor kinases, or GPCR β-arrestin recruitment. The specific parental cell line chosen determines the assay type. Then create an ED-tagged target protein plasmid followed by transfection of this plasmid into the parental cell line containing EA. Perform antibiotic selection, detect the level of expression of the two fusion proteins (optional), and perform the desired assay in the presence of a ligand.
Rapidly Create β-Arrestin, Tyrosine Kinase, and Translocation Assays Using Engineered Cells
PathHunter® Parental Cell Lines
Utilize engineered PathHunter parental cells to rapidly develop β-arrestin recruitment, SH2-protein recruitment, or translocation EFC cell-based assays after introducing your protein of interest. These parental cell lines provide the ability to study β-arrestin recruitment with your favorite GPCR, analyze tyrosine kinase activity and SH2-recruitment, or investigate trafficking of your target protein to the plasma membrane, nucleus, or endosome.
