This antibody reacts with CD93 antigen. mNI-11 has been reported to induce intercellular adhesion of LPS-stimulated monocyte (U937) cells as well as inducing the adhesion of these cells to an endothelial (HUVEC) cell layer and rapid spread formation in HUVECs.
CD93, also known as C1qRp, is a 100-125 kDa type I membrane protein that is a receptor for the complement protein C1q. CD93 has also been shown to act as a receptor for mannose-binding lectin and surfactant protein A. CD93 is expressed on the surface of monocytes, granulocytes, and endothelial cells, and expression is increased by TNF-α or GM-CSF. CD93 is involved in ligand-mediated enhancement of phagocytosis and intercellular adhesion.Synonyms: C1q receptor, C1q/MBL/SPA receptor, CDw93, Complement component 1 q subcomponent receptor 1, Complement component C1q receptor, MBL receptor, MXRA4, Matrix-remodeling-associated protein 4, SPA receptor
