Human FRS3 ELISA Kit (HUFI04234)

Fibroblast growth factor receptor substrate 3 (FRS3) is quantified with this Assay Genie ELISA Kit, an immunometric assay that measures the adaptor protein linking activated FGFR tyrosine kinases to downstream MAPK and PI3K signaling cascades.

Researchers employ the assay to study FGF signaling in neuronal development, stem cell differentiation, and cancer biology, where dysregulated FRS3 activity contributes to aberrant pathway output.

The kit contains pre-coated microwell strips, lyophilized standard, biotinylated detection reagent, horseradish peroxidase conjugate, wash buffer concentrate, substrate, and stop solution, all sized for 96 individual determinations per run.

Reagents are shipped refrigerated; reconstituted standards and unused strips should be stored frozen at -20°C to maintain antibody binding capacity through the stated shelf life.

The capture antibody is validated for specific detection of human FRS3, supporting clean quantitation in FGF pathway research. The assay is intended for research use only in vitro and is configured for measurement in cell culture supernatant, tissue lysate, and standard biological specimens.
