CD55, also known as decay-accelerating factor (DAF), is a glycoprotein that plays a crucial role in the regulation of the complement system. It inhibits the formation and accelerates the decay of C3 convertases, thereby protecting host cells from complement-mediated lysis. CD55 is involved in various signaling pathways, including the PI3K-Akt pathway.
Dysregulation of CD55 has been associated with several diseases, such as paroxysmal nocturnal hemoglobinuria (PNH) and age-related macular degeneration (AMD). In drug development, targeting CD55 shows potential for treating these complement-related disorders. Some monoclonal antibodies are under investigation to modulate its function.

IHC image of CSB-RA440943A0HU diluted at 1:100 and staining in paraffin-embedded human lung tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.
