Storage: In the dark at 4-8ºC
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 (1). It consits 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 (2)
MBL purified from human donor plasma and adsorbed onto aluminum hydroxide.
HYB 131-14 is specific for human MBL from plasma or serum, but cross-reacts strongly with MBL from horse and swine.
Not determined (presumably reacts with the carbohydrate recognition domain).
HYB 131-14 reacts strongly with human, horse and swine serum, when captured on an mannan coat in ELISA. A weaker reaction is seen when HYB 131-14 is used as a detection antibody for human MBL coated directly onto the microtiter plate.
| Method | Usability | Dilution guideline | References |
| ELISA | Yes | 1/250 | |
| Immunoblotting | Yes | ||
| Immunohistochemistry | Not determined |
The dilution guideline for ELISA is based on use as detection antibody for antigen coated at 0.3 µg/mL together with human albumin 8.5 µg/mL. Users should determine the optimal dilutions for their own purposes.
