The CD8 antigen is a cell surface glycoprotein found on most cytotoxic T lymphocytes that mediates efficient cell-cell interactions within the immune system. The CD8 antigen, acting as a coreceptor, and the T-cell receptor on the T lymphocyte recognize antigen displayed by an antigen-presenting cell (APC) in the context of class I MHC molecules. The functional coreceptor is either a homodimer composed of two alpha chains, or a heterodimer composed of one alpha and one beta chain. Both alpha and beta chains share significant homology to immunoglobulin variable light chains. This gene encodes the CD8 alpha chain isoforms. Two alternative transcripts encoding distinct isoforms, one membrane associated and one secreted, have been identified
IHC shows positive staining in paraffin-embedded human tonsil.
CD8α Mouse mAb was used at 1/1000 dilution, followed by a Goat Anti-mouse IgG H&L (HRP) 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 stomach.
CD8α Mouse mAb was used at 1/1000 dilution, followed by a Goat Anti-mouse IgG H&L (HRP) ready to use.
Counterstained with hematoxylin.
Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
ICC shows positive staining in PBMC cells. Anti-CD8a antibody was used at 1/500 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. The cells were fixed with 4% PFA and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue).Counterstain with tubulin (Red).
IF shows positive staining in paraffin-embedded human tonsil. Anti- CD8a antibody was used at 1/1000 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).Counterstain with CD3 epsilon (S0B2132, Red). Heat mediated antigen retrieval with EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
