  • Application notesIs unsuitable for ICC or IHC-Fr.
  • Target

    • FunctionCould play a role in phagocytic activities of tissue macrophages, both in intracellular lysosomal metabolism and extracellular cell-cell and cell-pathogen interactions. Binds to tissue- and organ-specific lectins or selectins, allowing homing of macrophage subsets to particular sites. Rapid recirculation of CD68 from endosomes and lysosomes to the plasma membrane may allow macrophages to crawl over selectin-bearing substrates or other cells.
    • Tissue specificityHighly expressed by blood monocytes and tissue macrophages. Also expressed in lymphocytes, fibroblasts and endothelial cells. Expressed in many tumor cell lines which could allow them to attach to selectins on vascular endothelium, facilitating their dissemination to secondary sites.
    • Sequence similaritiesBelongs to the LAMP family.
    • Post-translational
      N- and O-glycosylated.
    • Cellular localizationCell membrane and Endosome membrane. Lysosome membrane.

    Thank you for your inquiry.

    I apologise for the delay. I had to wait for an answer from the source of these two products.

    I can now confirm that the concentration of ab783 is 10ug/ml and ab844 is approximately 2-4ug/ml.
