  • Product overview

    Abcam’s MBL (Mannose-Binding Lectin) Human ELISA Kit (ab193709) is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human MBL in sera, plasma and cell culture supernatants.

    This assay employs an antibody specific for Human MBL coated on a 96-well plate. Standards and samples are pipetted into the wells and the immobilized antibody captures MBL present in the samples. The wells are washed and biotinylated anti-Human MBL antibody is added. After washing away any unbound biotinylated antibody, an HRP-conjugated streptavidin is pipetted to the wells. After incubation, the wells are again washed, followed by the addition of a TMB substrate solution to the wells. Color will develop in proportion to the amount of MBL bound in each well. Addition of the Stop Solution will change the color from blue to yellow, and the intensity of the color is measured at 450 nm.

  • 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.
  • Sequence similarities

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

    The coiled-coil domain mediates trimerization.
  • Cellular localization
