背景介绍
  • CD8A encodes the CD8 alpha chain of the αβT cells, proposed as a quantifiable indicator for CD8+ CTL recruitment or activity assessments and a robust biomarker for responses to anti-PD-1/PD-L1 therapy. In NK-cells, the presence of CD8A homodimers at the cell surface provides a survival mechanism allowing conjugation and lysis of multiple target cells. CD8A homodimer molecules also promote the survival and differentiation of activated lymphocytes into memory CD8 T-cells.

  • 流式分析

    • Flow cytometric analysis of human PBMC (human peripheral blood mononuclear cell) labelling CD8α antibody at 1/2000 dilution (0.1 μg) / (Red) compared with a Mouse monoclonal IgG (Black) isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue). Goat Anti - Mouse IgG Alexa Fluor® 488 was used as the secondary antibody. Then cells were stained with CD4 - Alexa Fluor® 488 separately. Gated on total viable cells.

  • 免疫组化

    • IHC shows positive staining in paraffin-embedded human tonsil. Anti-CD8α antibody was used at 1/200 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.

    • IHC shows positive staining in paraffin-embedded human spleen. Anti-CD8α antibody was used at 1/200 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.

  • 免疫荧光

    • IF shows positive staining in paraffin-embedded human tonsil. Anti-CD8α antibody was used at 1/100 dilution (Green) and incubated overnight at 4°C. Goat polyclonal Antibody to Mouse IgG - H&L (Alexa Fluor® 488) was used as secondary antibody at 1/1000 dilution. Counterstained with DAPI (Blue). Heat mediated antigen retrieval with EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
