Used in immunological research to study plasmacytoid dendritic cell function and interferon responses in non-human primate models. Enables detection and quantification of CLEC4C interactions in binding assays and flow cytometry. Supports development of therapeutic antibodies by serving as a control or target in functional studies. Facilitates investigation of viral immune evasion mechanisms due to CLEC4C's role in pathogen recognition. The Fc tag allows for easy purification and detection using anti-Fc reagents.
