  • Product overview

    Abcam’s SIGLEC5 Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human SIGLEC5 in serum, plasma and cell culture supernatants.

    This assay employs an antibody specific for Human SIGLEC5 coated on a 96-well plate. Standards and samples are pipetted into the wells and SIGLEC5 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human SIGLEC5 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of SIGLEC5 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

  • Research areas
  • Relevance
    Putative adhesion molecule that mediates sialic-acid dependent binding to cells. Binds equally to alpha2,3-linked and alpha2,6-linked sialic acid. The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface. This molecule is expressed by monocytic/myeloid lineage cells. Found at high levels in peripheral blood leukocytes, spleen, bone marrow and at lower levels in lymph node, lung, appendix, placenta, pancreas and thymus. Expressed by monocytes and neutrophils but absent from leukemic cell lines representing early stages of myelomonocytic differenciation.
