Human FXYD3 ELISA Kit (HUFI04202)

The Assay Genie ELISA kit enables quantitative measurement of FXYD3, a single-pass transmembrane protein belonging to the FXYD family of small ion transport regulators that modulate Na+/K+ ATPase activity. FXYD3 has attracted considerable research interest as a candidate biomarker, with elevated expression documented in HER2-positive breast tumors, colorectal adenocarcinoma, pancreatic ductal carcinoma, and certain prostate cancer cell lines.

Built around a quantitative immunoassay workflow, the kit supports reproducible FXYD3 detection in standard research settings. Each package includes a pre-coated 96 Assays plate along with reagents needed to generate a standard curve and run samples. Investigators studying tumor biology, ion transport physiology, or biomarker validation may use this kit for comparative expression studies.

Sample handling: prepared specimens should be stored refrigerated until processed. For longer term archiving, samples may be frozen and aliquoted to minimize repeated freeze-thaw cycles, which can compromise protein integrity and downstream measurements. The protocol outlines recommended dilutions, incubation times, and data interpretation guidelines.

Intended for research use only and validated for in vitro studies, this kit is not intended for diagnostic procedures. Each unit contains materials sufficient for one full 96 Assays plate. Quality control data, including inter-assay and intra-assay precision metrics, are provided with the shipment.
