Porcine CD8, a type I transmembrane glycoprotein, is expressed as either a CD8 alpha alpha homodimer or a CD8 alpha beta heterodimer. It is found on most thymocytes, and on the 'suppressor/cytotoxic' subpopulation of peripheral T cells. CD8 functions primarily as a co-receptor with MHC Class I-restricted T-cell receptors in antigen recognition. MAb 76-2-11 reacts with the CD8 alpha chain. (1-3)

FAQs for CD8 alpha Antibody (NBP1-28237). (Showing 1 - 5 of 5 FAQ).

  1. 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.   
  2. 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.
  3. 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. 
  4. 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.
  5. 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.
