Mannan Binding Lectin (MBL)
Mannan-binding lectin (MBL) is an acute-phase, carbohydrate-binding serum protein secreted by the liver that plays a central role in the innate immune system. Structurally MBL is a C1q-like molecule that in association with MBL associated serine proteases (MASPs) binds to surface carbohydrates on bacteria, fungi, viruses and protozoa making them accessible for phagocytosis through MBL receptors or by activating the complement cascade via the recently elucidated MBL or lectin pathway.
Enzyme Immunoassay. The test uses a monocolonal antibody against the oligomeric MBL carbohydrate-binding domain for both capture and detection. The specificity of this monoclonal antibody for oligomeric MBL has been previously reported. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.
