Fc Receptor Collections: Designed for Half-Life Assessment and In Vitro Functional Validation

To support the efficient screening and validation of antibody drugs, we have created a comprehensive suite of Fc receptor-related products, including FcR proteins, FcR binding kits (TR-FRET) and overexpressing cell lines. Our FcR proteins are characterized for binding affinity using SPR and BLI, guaranteeing bioactivity and are provided with detailed protocols at no extra cost. With purity consistently above 95% by SDS-PAGE and over 90% by SEC-MALS, as well as high-efficiency, site-specific Avitag™ biotinylation, these proteins deliver robust and reliable results across a range of research applications. Expressed using HEK293 cells and available in multiple species variants, they ensure exceptional stability and broad compatibility. The FcR binding kits are designed for high-throughput screening — eliminating complex washing steps and delivering results within an hour. Rigorously validated with diverse antibody subtypes and drugs, with strict quality controls ensuring outstanding batch-to-batch consistency. They are highly sensitive, delivering precise and reproducible results with minimal matrix interference. In addition, our overexpression cell lines, offer enhanced activity and wide assay windows. Each cell line comes with full application data, verified stability, documented quality assurance and parental cells traceable to globally recognized and licensed banks, supporting both research and regulatory compliance needs. Choosing our FcRs portfolio equips antibody discovery and development workflows with reliability, convenience and scientific rigor.
