Retrogenix provides a fast, accurate and effective solution for primary receptor identification and specificity screening of antibodies, protein ligands, CAR T cells and other biotherapeutics.  Biologically-relevant targets are identified by screening for interactions against the most comprehensive set of plasma membrane and tethered secreted proteins that are expressed in human cells. This informs lead selection, assists with safety assessment and has generated data used in patent applications as well as regulatory submissions in multiple regions, including the US, EU, Japan & China.
