Specifications

Our Abpromise guarantee covers the use of ab220591 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • Applications

    SDS-PAGE

  • Endotoxin level

    < 1.000 Eu/µg
  • Purity

    > 95 % SDS-PAGE.

  • Form

    Lyophilised
  • Concentration information loading...

Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. Store at -80°C. Avoid freeze / thaw cycle.

    pH: 7.50
    Constituents: 0.61% Tris, 0.75% Glycine, 5% Trehalose, Sodium chloride, L-Arginine

    Lyophilized from 0.22 µm filtered solution.
    5-10% trehalose is commonly used for freeze drying, and after reconstitution, the trehalose is mostly about 3-5%

  • Reconstitution
    It is recommended to reconstitute the lyophilized protein in sterile deionized water to a final concentration of 1mg/ml. Solubilize for 30 to 60 minutes at room temperature with occasional gentle mixing. Carrier protein (0.1% HSA or BSA) is strongly recommended for further dilution and long term storage.

  • Function

    May participate in the regulation of T-cell-mediated immune response. May play a protective role in tumor cells by inhibiting natural-killer mediated cell lysis as well as a role of marker for detection of neuroblastoma cells. May be involved in the development of acute and chronic transplant rejection and in the regulation of lymphocytic activity at mucosal surfaces. Could also play a key role in providing the placenta and fetus with a suitable immunological environment throughout pregnancy. Both isoform 1 and isoform 2 appear to be redundant in their ability to modulate CD4 T-cell responses. Isoform 2 is shown to enhance the induction of cytotoxic T-cells and selectively stimulates interferon gamma production in the presence of T-cell receptor signaling.
  • Tissue specificity

    Ubiquitous but not detectable in peripheral blood lymphocytes or granulocytes. Weakly expressed in resting monocytes. Expressed in dendritic cells derived from monocytes. Expressed in epithelial cells of sinonasal tissue. Expressed in extravillous trophoblast cells and Hofbauer cells of the first trimester placenta and term placenta.
  • Sequence similarities

    Belongs to the immunoglobulin superfamily. BTN/MOG family.
    Contains 2 Ig-like C2-type (immunoglobulin-like) domains.
    Contains 2 Ig-like V-type (immunoglobulin-like) domains.
  • Cellular localization

    Membrane.
  • Information by UniProt

Images

  • SDS-PAGE analysis of reduced ab220591 stained overnight with Coomassie Blue.

    The reducing protein migrates as 60-66 kDa in SDS-PAGE due to glycosylation.
