This product gave a positive signal in CHO-PDL1 cells fixed with 4% formaldehyde (10 min)

Target

  • Function
    Involved in the costimulatory signal, essential for T-cell proliferation and production of IL10 and IFNG, in an IL2-dependent and a PDCD1-independent manner. Interaction with PDCD1 inhibits T-cell proliferation and cytokine production.
  • Tissue specificity
    Highly expressed in the heart, skeletal muscle, placenta and lung. Weakly expressed in the thymus, spleen, kidney and liver. Expressed on activated T- and B-cells, dendritic cells, keratinocytes and monocytes.
  • Sequence similarities
    Belongs to the immunoglobulin superfamily. BTN/MOG family.
    Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
    Contains 1 Ig-like V-type (immunoglobulin-like) domain.
  • Cellular localization
    Cell membrane and Endomembrane system.

Anti-PD-L1 antibody [28-8] (Alexa Fluor® 647) images

  • Ab209960 staining PDL1 in CHO-PDL1 cells. The lower panels demonstrate that ab209960 does not cross react with un-transfected CHO cells.

    The cells were fixed with 4% formaldehyde (10 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab209960 at 1/200 dilution (shown in red) and ab195887, Mouse monoclonal to alpha Tubulin (Alexa Fluor® 488), at 1/250 dilution (shown in green). Nuclear DNA was labelled with DAPI (shown in blue).

    Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

  • Overlay histgram showing CHO (blue line) and CHO-PD-L1 transfected (red line) cells stained with ab209960.

    The cells were incubated in 1x PBS / 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (ab209960, 1/100 dilution) for 30 min at 4ºC.

    Acquisition of >5,000 events were collected using a 17mW red Helium-Neon laser (633nm) and 660/20 bandpass filter.
