Human FNBP4 (Formin-binding protein 4) ELISA KIT (HUFI05221)

The Human FNBP4 ELISA Kit from Assay Genie enables quantitative detection of formin-binding protein 4 in human research samples. FNBP4 (also referred to as FBP21) is an intracellular adapter containing tandem WW domains that recognize proline-rich motifs. It participates in cytoskeletal remodeling via formin interaction, U4/U6.U5 tri-snRNP spliceosome assembly, and transcriptional co-activation. Published research has associated elevated FNBP4 expression with hepatocellular carcinoma proliferation, breast cancer cell invasion, and dysregulated WNT signaling, making this kit useful for oncology biomarker discovery, splicing factor studies, and cytoskeletal signaling investigations.

Reagents are supplied for one complete microplate experiment with a human-specific capture antibody that does not significantly cross-react with related formin-binding proteins. Store unopened kit components refrigerated at 4 degrees C, protected from light, and avoid repeated freeze-thaw cycles of reconstituted standards. Reconstituted working solutions should be aliquoted for single use. The well plate format allows parallel processing of standards and unknown samples with an assay run time suitable for routine laboratory workflows. Each kit is intended for research use only and supports applications including serum-based biomarker studies and mechanistic investigations of formin-mediated cytoskeletal dynamics.
