Our Abpromise guarantee covers the use of ab25294 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|Flow Cyt||Use 0.2µg for 106 cells.|
|IHC-Fr||Use at an assay dependent concentration.|
|IP||Use at an assay dependent concentration.
In vivo and in vitro depletion of CD8alpha+ cells: Use at an assay dependent dilution. Fractionation of CD8alpha+ T cells: Use at an assay dependent dilution.
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.
modificationsAll 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.
