Used in research to study folate receptor biology in non-human primate models, particularly in immunology and oncology. Supports the development of targeted therapies by enabling the detection and quantification of FOLR1 interactions in cellular assays. The Fc tag facilitates purification and enhances detection using anti-Fc secondary reagents. Commonly applied in ELISA, flow cytometry, and binding studies to evaluate monoclonal antibody candidates targeting folate receptors. Helps assess cross-reactivity and pharmacokinetics in preclinical studies involving cynomolgus and rhesus macaques.
