CD8b Antibody, anti-human, PE-Vio® 615, REAfinity™，130-133-146，美天旎

Clone REA715 recognizes the human CD8b antigen, a single-pass type I membrane protein and member of the immunoglobulin superfamily, also known as T cell surface glycoprotein Lyt-3. The CD8 glycoprotein is expressed by thymocytes, mature T cells, and natural killer (NK) cells and has been implicated in the recognition of monomorphic determinants on major histocompatibility complex class I antigens and in signal transduction during the course of T cell activation. Both human and rodent CD8 antigens are comprised of two distinct polypeptide chains, alpha and beta. Most of peripheral blood CD8⁺ T lymphocytes express the CD8a/CD8b heterodimer, while CD8⁺CD16⁺ natural killer cells and CD8⁺ T cell receptor γ/δ⁺ T lymphocytes express only the CD8a/CD8a homodimer. CD8b can therefore be used to selectively bind to CD8⁺ T cells while excluding CD8⁺ NK cells.

Additional information: Clone REA715 displays negligible binding to Fc receptors.
