Human GPBP1 ELISA Kit (HUFI07850)

The Assay Genie immunoassay kit quantifies GPBP1 (Goodpasture antigen-binding protein 1), a ceramide transfer protein also annotated as CERT or COL4A3BP, that shuttles ceramide from the endoplasmic reticulum to the trans-Golgi and supports nonvesicular lipid trafficking in mammalian cells. Researchers investigating sphingolipid metabolism, basement membrane biology, and Goodpasture-related autoimmunity use quantitative GPBP1 measurements to explore links between ceramide homeostasis and renal or vascular pathology, while oncology labs study the protein's emerging role in tumor cell survival and stress response signaling. Supplied as a 96 Assays pack with a colorimetric readout, the kit is intended for research use only and supports work on cell culture supernatants, tissue lysates, and matched human donor cohorts. Each run relies on paired antibodies immobilised on a microplate, with bound analyte revealed through an enzyme-substrate reaction read on a standard plate reader, yielding values that can be compared across longitudinal studies of disease progression or treatment response.
