Human Protectin (CD59) ELISA Kit

CD59, also called Protectin, is a glycosylphosphatidylinositol-anchored cell surface glycoprotein that restricts complement-mediated lysis by blocking assembly of the membrane attack complex on host cells. The Human Protectin (CD59) ELISA Kit from Assay Genie enables quantitative measurement of this complement regulator in human research specimens, supporting studies in immunology, hematology, and membrane biology.

This Assay Genie kit is configured in a microplate format and uses an absorbance-based detection read-out. The assay is intended for in vitro research use only and is validated for human-derived sample types including blood-derived fractions and cell lysates. Researchers investigating paroxysmal nocturnal hemoglobinuria, complement regulatory dysfunction, autoimmune disease mechanisms, and changes in circulating CD59 levels across treatment regimens rely on quantitative ELISA readouts to track this analyte over time.

Each kit is supplied with all reagents required to perform the immunoassay, including a single microplate and accompanying buffers. Components should be refrigerated upon arrival and protected from light to maintain stability. Full procedural detail, recommended dilution schemes, and assay-specific performance characteristics are provided in the product insert packaged with each lot.
