CD8a (PerCP)

CD8a is a 32kD glycoprotein also known as T8, Lyt2, Ly-2, and CD8α. CD8a is a member of the immunoglobulin superfamily expressed on most thymocytes, subset of mature T cells, most NK cells, macrophages, and some activated CD4+ T cells (not resting). CD8a forms heterodimers with the CD8beta chain (CD8b) on the surface of most thymocytes, while mature peripheral T lymphocytes express almost exclusively the CD8 alpha beta heterodimer. Intestinal intraepithelial lymphocytes express CD8a without CD8b. CD8 is an antigen co-receptor on T cells that interacts with MHC class I on antigen-presenting cells or epithelial cells. CD8 participates in T cell activation through its association with the T cell receptor complex and protein tyrosine kinase lck (p56lck).||Applications: |Suitable for use in Flow Cytometry. Other applications not tested.||Recommended Dilution:|Flow Cytometry: 2ul or 5ul of antibody/test (million cells in 100ul staining volume or per 100ul of whole blood).|Optimal dilutions to be determined by the researcher.||Storage and Stability:|May be stored at 4°C. For long-term storage, aliquot and store at 4°C. Do not freeze. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer. PerCP conjugates are sensitive to light.
