| IP | Use at an assay dependent concentration. | |
| Functional Studies | Use at an assay dependent concentration. (In vivo and in vitro depletion of CD8a+ cells): Use at an assay dependent dilution.Fractionation of CD8a+ T cells: Use at an assay dependent dilution. |
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
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.

Tissue was fixed with acetone and then blocked with 5% serum for 1 hour at 25°C followed by incubation with the primary antibody at a 1/250 dilution for 12 hours at 4°C. A goat anti-rat IgG conjugated to Alexa Fluor®594 was used as secondary antibody at a 1/250 dilution.
