    See all CD8 alpha primary antibodies
  • Description
    Rat monoclonal [YTS 169AG 101HL] to CD8 alpha (FITC)
  • ConjugationFITC. Ex: 493nm, Em: 528nm
  • Specificityab112219 reacts with CD8alpha found on Mouse thymocytes and Mouse cytotoxic/suppressor T cells. It does not bind to Mouse helper/inducer T cells. It binds to T lymphocytes from all Mouse strains regardless of phenotypic expression (i.e. reacts with T lymphocytes from mouse strains expressing the Ly 2.1 or Ly 2.2 phenotype).

Our Abpromise guarantee covers the use of ab112219 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use at an assay dependent concentration. Antigen retrieval is required
Flow Cyt Use 0.1µg for 106 cells. ab136125-Rat monoclonal IgG2b, is suitable for use as an isotype control with this antibody.


  • 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 carboxyl-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.
