    Mouse OT-I primary CTL cells were stained with purified anti-mouse CD8a primary antibody at 1:50 dilution in PBS/1%NGS incubated O/N at 4°C, detected with anti-rat IgG2b FITC at 1:2000 dilution for 1hr at room temperature (green), plus DAPI staining for nuclei (blue). Imaged with a Zeiss 200M deconvolution microscope (deconvolution applied). Negative control was anti-rat IgG2b isotype control plus secondary antibody, same conditions.

Description

CD8, also known as Lyt-2, Ly-2, or T8, consists of disulfide-linked α and β chains that form the α(CD8a)/β(CD8b) heterodimer and α/α homodimer. CD8a is a 34kD protein that belongs to the immunoglobulin family. The CD8 α/β heterodimer is expressed on the surface of most thymocytes and a subset of mature TCR α/β T cells. CD8 expression on mature T cells is non-overlapping with CD4. The CD8 α/α homodimer is expressed on a subset of γ/δ TCR-bearing T cells, NK cells, intestinal intraepithelial lymphocytes, and lymphoid dendritic cells. CD8 is an antigen co-receptor on T cells that interacts with MHC class I on antigen-presenting cells or epithelial cells. CD8 promotes T cell activation through its association with the TCR complex and protein tyrosine kinase lck.

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 ≤ 0.25 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Additional reported applications (for the relevant formats) include: partial inhibition of T-cell responses to IL-2 and cytotoxic induction of splenic T cells1, immunohistochemistry of acetone-fixed frozen sections2, and immunofluorescence. The 5H10-1 antibody competes with 53-6.7 antibody (Cat. No. 100702) for binding to thymocytes1.

Clone 5H10-1 is not recommended for immunohistochemistry of formalin-fixed paraffin sections.
