Human CD68 / SR-D1 Protein, Fc Tag

  • Synonym
  • Source
    Human CD68, Fc Tag (MAN-H5258) is expressed from human 293 cells (HEK293). It contains AA Asn 22 - Ser 319 (Accession # AAH15557).
    Predicted N-terminus: Asn 22
  • Molecular Characterization
    CD68(Asn 22 - Ser 319) AAH15557

    This protein carries a human IgG1 Fc tag at the C-terminus.

    The protein has a calculated MW of 59.2 kDa. The protein migrates as 110-120 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    No activity loss is observed after storage at:

    1. 4-8°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.

  • Background
    CD antigen CD68 is also known as Macrosialin, Gp110, which belongs to the LAMP family. CD68 / Macrosialin is highly 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. CD68 / Macrosialin could play a role in phagocytic activities of tissue macrophages, both in intracellular lysosomal metabolism and extracellular cell-cell and cell-pathogen interactions. CD68 / Macrosialin 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.
