SpecificityAb41327 recognises Pekin duck CD8 alpha (CD8a), shown to be expressed by thymocytes, splenocytes, peripheral lymphoid cells and the vast majority of bursal cells. We have data to indicate that this antibody may not cross react with Chicken. However, this has not been conclusively tested and expression levels may vary in certain cell lines/tissues.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application notesFlow Cyt: Use 10ul of the suggested working dilution to label 106 cells in 100ul.
IP: Use at an assay dependent dilution.
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
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.
