Human HPS4 ELISA Kit (HUFI03896)

Quantify human HPS4 protein levels in research specimens with this in vitro immunoassay kit from Assay Genie, supplied in a microplate format for processing 96 determinations per run. The kit supports investigations into Hermansky-Pudlak syndrome and related lysosome-related organelle biogenesis disorders, since HPS4 encodes a subunit of the BLOC-3 complex and aberrant expression is associated with oculocutaneous albinism, platelet storage pool deficiency, and progressive pulmonary fibrosis in affected individuals.

Each research-use only kit includes all reagents required for a colorimetric enzyme-linked immunosorbent assay, with reference standards generated from recombinant HPS4 calibrators included in the package. Specimens of human serum or plasma prepared under standard collection protocols are suitable input material, and the assay workflow accommodates appropriate dilution series and biological replicates.

Typical applications include biomarker validation in patient cohorts, characterization of patient-derived cell lines, and screening of compounds that modulate melanosome or platelet dense granule trafficking. Researchers working on Hermansky-Pudlak syndrome subtypes, idiopathic pulmonary fibrosis, and broader studies of BLOC complex assembly can incorporate the kit alongside assays for cytokines, fibrotic markers, or related trafficking proteins.

The kit is supplied refrigerated and should be stored at the temperature indicated on the product insert until first use, then protected from light between runs. All work must be performed in accordance with the supplied protocol, and quantitative readouts should be interpreted against the standard curve within the validated linear range of the assay.
