Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 33, 65 kDa (predicted molecular weight: 33 kDa).
IHC-P 1/40. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.


  • 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.

  • ab64116 (1:40) staining CD80 in paraffin-embedded mouse lymph node tissue (left panel) using an automated system (Ventana Discovery).  Right-hand panel shows negative control (no primary antibody).  
    Using this protocol there is strong membrane staining, of activated B cells in the germinal centres.  What appear to be scattered activated B cells or possibly plasma cells in the interfollicular areas of the lymph node and blood vessels.

    Sections were rehydrated and antigen retrieved in CC1 Cell Conditioning Buffer using Ventana Extended Retrieval programme. Slides were blocked in 3% H2O2 / 4 min / 37°C and incubated with ab64116 (1:40 dilution / 1 hour / 37°C). Sections then blocked (4mins / 37°C) and incubated with Dako swine anti-rabbit antibody (1:50, 28 min / 37°C). Staining was amplified and detected by incubation with Ventana Streptavidin ABC system (16 min / 37°C) and Ventana DAB map reagent (8

    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) (ab65484) at 1/3000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 33 kDa
    Observed band size : 33,65 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 70 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 30 seconds

    CD80 has a predicted molecular weight of 33 kDa, however it is predicted to be extensively glycosylated (SwissProt data). The band seen at 65 kDa is consistent with the banding pattern observed for other commercially available antibodies to CD80. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
