Lectin-like molecules
Mannose-Binding Lectin (MBL) also called mannan-binding lectin, mannose- or mannan-binding protein (MBP) is a member of the collectins and an important element in innate immunity. It forms a complex with C1r/C1s like serine proteases designated MASP that proteolytically cleave C4, C2 and C3. MBL is able to activate the complement pathway independent of the classical and alternative pathways.
MBL exhibits complement-dependent anti-bacterial activity and acts directly as an opsonic and therefore plays an important role in innate immunity. MBL-deficiency has been related to a number of diseases. Measurement of functional MBL is of interest in studies on bacterial infections, autoimmune diseases, cancer, HIV, transplantation, atherosclerosis, cystic fibrosis, transplantation and many other diseases.
HBT offers antibodies and assays to human MBL, unique assays for mouse MBL-A and MBL-C, MASP2, and MBL/MASP2.
