Human FSCN3 ELISA Kit (HUFI04236)

FSCN3 encodes Fascin-3, the third member of the human fascin family of actin-bundling proteins. Whereas FSCN1 is broadly expressed across tissues and FSCN2 is enriched in retina and testis, FSCN3 shows a much narrower expression profile, with transcripts concentrated largely in testis tissue and contributing to actin filament organization during spermatid differentiation. Mutations and altered expression in fascin family members have been linked to defects in cell migration, filopodia formation, and cellular protrusion dynamics, making the protein a relevant target in cytoskeletal and reproductive biology research.

This quantitative immunoassay from Assay Genie is calibrated for use with human serum or plasma specimens and supplies 96 individual determinations per plate. Detection relies on an absorbance-based readout on a standard microplate reader, and the kit is configured for research use only in laboratory settings. Applications include quantitative measurement of circulating Fascin-3 levels, biomarker screening in reproductive or inflammation studies, and supporting investigations into testis-specific cytoskeletal protein expression.
