Human UPK3B ELISA Kit (HUFI05793)

Uroplakin 3B (UPK3B) is a tetraspan transmembrane protein embedded in the asymmetric unit membrane that covers the apical surface of terminally differentiated urothelial cells. Measuring this urothelium-specific marker in human biospecimens supports research into bladder epithelial differentiation, urothelial carcinoma progression, and the molecular changes that accompany lower urinary tract disorders including interstitial cystitis and bladder outlet obstruction.

This quantitative immunoassay kit from Assay Genie is supplied with a microplate and all buffers, standards, capture reagents, and detection components needed for a complete experimental run. The procedure follows an incubation-based plate workflow with chromogenic signal development, and the product is intended for research use only in laboratories studying urothelial markers, tumor biology, or urinary tract pathology.

The kit is shipped refrigerated, and components should be handled according to the enclosed datasheet. Standard precautions include protection from light for chromogenic substrates, aliquoting of stock reagents to limit repeated freeze-thaw cycles, and storage at cool temperatures to preserve antibody and conjugate activity across the product's shelf life.
