CD8b or CD8β antigen is also known as T8, Lyt2, Ly-2, and CD8β. It is a member of the immunoglobulin superfamily expressed on most thymocytes, and some mature T cell subsets. CD8β forms heterodimers with the CD8α chain (CD8a). CD8 is an antigen co-receptor on T cells that interacts with MHC class I on antigen-presenting cells. CD8 participates in T cell activation through its association with the T cell receptor complex and protein tyrosine kinase lck (p56lck).

- Recommended Usage
-
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.5 µg per million cells in 100 µL volume. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
-
Based on in-house testing, clone QA20A40 reacts with an epitope formed by a heterodimer of human CD8a and CD8b chains, while clone S21011A reacts to an epitope exclusively present on human CD8b.
