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

Application Abreviews Notes
WB Use at an assay dependent concentration. Detects a band of approximately 55-60 kDa (predicted molecular weight: 35 kDa).


  • Function

    Involved in the costimulatory signal essential for T-lymphocyte activation. T-cell proliferation and cytokine production is induced by the binding of CD28 or CTLA-4 to this receptor.
  • Tissue specificity

    Expressed on activated B-cells, macrophages and dendritic cells.
  • Sequence similarities

    Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
    Contains 1 Ig-like V-type (immunoglobulin-like) domain.

    Lane 3 : P815 (mouse mastocytoma mast cell line) whole cell lysate

    Lysates/proteins at 10 µg per lane.

    All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/20000 dilution

    Predicted band size: 35 kDa
    Observed band size: 55-60 kDa
    why is the actual band size different from the predicted?

    Exposure time: 26 seconds

    Blocking/Dilution buffer: 5% NFDM/TBST.

    The molecular mass observed is consistent with what has been described in the literature (PMID: 7544014, PMID: 9079798); 55-60 kDa is due to glycosylation (PMID: 9654121).

    Negative control: P815 (PMID: 9237108).

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab238481).
