Application Abreviews Notes
  • Application notesIHC-P: 1/25 - 1/50. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.

    Not yet tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • FunctionIdentifies cytotoxic/suppressor T-cells that interact with MHC class I bearing targets. CD8 is thought to play a role in the process of T-cell mediated killing. CD8 alpha chains binds to class I MHC molecules alpha-3 domains.
    • Involvement in diseaseDefects in CD8A are a cause of familial CD8 deficiency (CD8 deficiency) [MIM:608957]. Familial CD8 deficiency is a novel autosomal recessive immunologic defect characterized by absence of CD8+ cells, leading to recurrent bacterial infections.
    • Sequence similaritiesContains 1 Ig-like V-type (immunoglobulin-like) domain.
    • Post-translational
      All of the five most C-terminal cysteines form inter-chain disulfide bonds in dimers and higher multimers, while the four N-terminal cysteines do not.
    • Cellular localizationSecreted and Cell membrane.
    • Information by UniProt
    • Database links
    • FormCD8 beta tissue specificity: Isoform 1, isoform 3, isoform 5, isoform 6, isoform 7 and isoform 8 are expressed in both thymus and peripheral CD8+ T-cells. Expression of isoform 1 is higher in thymus CD8+ T-cells than in peripheral CD8+ T-cells. Expression of isoform 6 is higher in peripheral CD8+ T-cells than in thymus CD8+ T-cells. CD8 beta PTM: Phosphorylated as a consequence of T-cell activation.
