In the chicken, the CD8 molecule is present in two forms: (i) a homodimer of two alpha chains, and (ii) a heterodimer of an alpha chain and a beta chain. (1) While the vast majority of CD8+ cells in the thymus, spleen, and blood of adult chickens express both CD8alpha- and CD8beta-chains, a relatively large proportion of the CD8+ TCR- gamma delta cells in the spleens of embryos and young chicks express only the alpha-chain of CD8. Among intestinal epithelial lymphocytes, the major CD8+ T cell populations present in mice are conserved, but there is a population of TCR-gamma delta CD8 alpha beta cells in the chicken that is not found in rodents. (1,3) Chicken CD8 is expressed on approximately 80% of thymocytes, 15% of blood mononuclear cells and 50% of spleen cells, but <1% of cells in the bursa and bone marrow. (1,2) MAb CT-8 recognizes the CD8alpha chain.1

FAQs for CD8 alpha Antibody (NBP1-28271). (Showing 1 - 5 of 5 FAQ).
I'm looking for a good anti CD8 antibody working on immunofluorescence on murine tumoral tissue fixed in paraformaldehyde, cryoprotected with sucrose, frozen in OCT medium and sectioned with a cryostat.
I would recommend our CD8 alpha antibody NBP1-49045, it is guaranteed to work in IHC-P and and IHC-FR.
How do I know if this will actually work in IHC?
This CD8 alpha antibody has been validated in IHC and has been cited in a paper where it was used in IHC. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3387923/
Will this CD8 alpha antibody work for rabbit in IHC-FR?
Unfortunately this CD8 alpha antibody has not yet been validated in rabbit and there no sequence info in uniprot yet so we can't speculate based on homology. You may want to take advantage of our innovator's reward program which will allow you to test in rabbit without any financial risk.
Does this CD8 alpha antibody detect both forms of CD8?
Both the alpha - beta heterodimer as well as the alpha - alpha homodimer are detected by the (53-6.7) CD8 alpha antibody.
Would you recommend your CD8 alpha antibody as a T-Cell marker?
Yes this CD8 alpha anitbody has been cited in a study where it was used in FACS to separate out CD8+ T-cells. Please see the references tab PMID: 1608966. It is important to note that our CD8 alpha antibody may also stain mature dendritic cells and NK cells.
