  • Product overview

    Abcam’s Human MBL Oligomer ELISA Kit (ab207922) is an in vitro determination of oligomerized mannan-binding lectin in human serum or heparin plasma. For research use only.

    The assay is an ELISA performed in microwells coated with a monoclonal antibody against the MBL carbohydrate-binding domain. Bound MBL is detected with the same antibody that has been labeled with biotin, followed by development with horseradish peroxidase (HRP)-conjugated streptavidin and incubation with a chromogenic substrate. Comparison of the assay results with molecular size chromatography of MBL immunoreactivity in individual human serum samples suggests that the monoclonal antibody used is selective for MBL oligomers when used as both capture and detection antibody.

  • Notes

    Mannan-binding lectin (MBL, also called mannose binding lectin or mannose binding protein) is a multimeric carbohydrate-binding protein produced in the liver and secreted into the blood, where it constitutes an important element in innate immune defense against invading microorganisms. Its normally oligomerized forms are associated with specific serine proproteases (The MASPs) which are activated when MBL binds to microbial carbohydrate surfaces and in turn activate complement via the MBL or lectin pathway.

  • Research areas

  • Function

    Calcium-dependent lectin involved in innate immune defense. Binds mannose, fucose and N-acetylglucosamine on different microorganisms and activates the lectin complement pathway. Binds to late apoptotic cells, as well as to apoptotic blebs and to necrotic cells, but not to early apoptotic cells, facilitating their uptake by macrophages. May bind DNA.
  • Tissue specificity

    Plasma protein produced mainly in the liver.
  • Involvement in disease

    Note=There is an association between low levels of MBL2 and a defect of opsonization which results in susceptibility to frequent and chronic infections.
  • Sequence similarities

    Contains 1 C-type lectin domain.
    Contains 1 collagen-like domain.
