Mannan-binding lectin (MBL), also called mannose-binding lectin or protein, belongs to the C-type family of collectins, showing calcium-dependent binding to certain sugars. It consists of oligomers of triple-chain subunits and its binding and complement activating activities depend on its normal oligomerization. On binding to mannan-like microbial surface carbohydrates, MBL activates the complement system by means of its own lectin pathway, depending on the MBL-associated serine proteases (MASPs). Because of the presence of different structural and promoter alleles in the population, 12% or more of the population have low concentrations (<50ng/mL) of normally oligomerized, functional MBL in plasma or serum.

Application 1


HYB 131-11 reacts strongly with MBL. Strong reaction is seen in ELISA with MBL coated directly onto the microtiter well. In Western blotting HYB 131-11 reacts with human MBL in both its oligomerized state and as single protein chain of 26 kDa. HYB 131-11 can be used to measure MBL in plasma or serum and is specific for oligomerized MBL when used in combination with itself, but not with other MBL antibodies, when it also reacts with poorly oligomerized forrms (1,2).
Application 2


HYB 131-11 can be used in Western blotting (3).
Application 3

HYB 131-11 can be used in immunoprecipitation (3).
