Flow cytometric analysis of CD46 expression on human PBMCs (human peripheral blood mononuclear cells). Human PBMCs were stained with Brilliant Violet 421™ Mouse Anti-Human CD19 Antibody and either PerCP-Cy5.5 Mouse IgG2a, k Isotype Control (left panel) or SDT PerCP-Cy5.5 Mouse Anti-Human CD46 Antibody (right panel) at 2 μl/test treated with True-Stain Monocyte Blocker™. Flow cytometry and data analysis were performed using Agilent NovoCyte Quanteon and FlowJo™ software.

Background
CD46, also known as membrane cofactor protein (MCP), is a type I transmembrane glycoprotein expressed on almost all human nucleated cells that protects host tissues from complement-mediated injury by acting as a cofactor for factor I–mediated proteolytic inactivation of the complement fragments C3b and C4b, and also modulates adaptive immunity by driving IFN-γ–biased Th1 responses and subsequent IL-10–producing T-regulatory cell differentiation, while serving as a cellular receptor for multiple pathogens including measles virus, adenoviruses, HHV-6, and pathogenic Neisseria.
