Human CD55/DAF PharmaGenie ELISA Kit (SBRS0390)

Quantitative immunoassay for human complement regulator CD55, also known as Decay Accelerating Factor (DAF), manufactured by Assay Genie as part of the PharmaGenie research reagent line. The kit enables researchers to measure soluble CD55 in conditioned cell culture media, plasma-derived specimens, and serum-derived specimens, supporting studies in complement biology, autoimmune disease research, and investigations of GPI-anchored regulatory proteins such as CD55. CD55 limits complement activation by accelerating the decay of C3 and C5 convertases on host cell surfaces, and altered expression has been documented in paroxysmal nocturnal hemoglobinuria, certain solid tumors, and transplant-related immune injury, making reliable quantitation valuable across immunology, hematology, and oncology programs.

The kit is supplied as a complete set of reagents for ninety-six determinations in a microplate-based workflow, compatible with laboratory protocols requiring batched sample processing. All components are intended for research use only, and the configuration supports scientists working with human specimens to investigate complement-pathway biomarkers, thrombotic microangiopathies, and inflammatory signaling cascades.
