  • Function

    Identifies 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.
  • Tissue specificity

    Isoform 1, isoform 3, isoform 5, isoform 6, isoform 7 and isoform 8 are expressed in both thymus and peripheral CD8+ T-cells. Expression of isoform 1 is higher in thymus CD8+ T-cells than in peripheral CD8+ T-cells. Expression of isoform 6 is higher in peripheral CD8+ T-cells than in thymus CD8+ T-cells.
  • Sequence similarities

    Contains 1 Ig-like V-type (immunoglobulin-like) domain.
  • Post-translational

    Phosphorylated as a consequence of T-cell activation.
  • Cellular localization

    Secreted and Cell membrane.

Customer reviews and Q&As


Thank you for contacting us. As discussed on the phone, this antibody is not conjugated and in order to detect it you would therefore either need a secondary antibody or to conjugate the antibody itself. We have several secondary antibodies to choose from and a very useful search engine in order to identify exactly what your looking for, allowing you to choose the conjugate, species and a number of other factors: https://www.abcam.com/index.html?pageconfig=productmap&cl=918 If you would like help in choosing an appropriate antibody please do not hesitate to contact us. Alternatively you could directly conjugate the antibody itself using one of our conjugation kits: https://www.abcam.com/index.html?pageconfig=resource&rid=13148 Again, this can be used to attach the conjugate of your choice to the antibody for direct detection. I hope this information has been of help. If you have any further questions please do not hesitate to contact me again.
