The Mouse CD8a Monoclonal Antibody (FITC Conjugated) is a specialized tool for research involving CD8a, a key cell surface marker associated with cytotoxic T cells. This monoclonal antibody, clone 53-7.6, is specifically designed for use in flow cytometry applications, offering high sensitivity and specificity for detecting CD8a expression in mouse samples.CD8a is a crucial component of the immune system, primarily found on cytotoxic T cells that play a central role in immune responses against pathogens and abnormal cells. By targeting CD8a, researchers can effectively label and identify cytotoxic T cells in various experimental settings, providing valuable insights into immune function and response dynamics.
The FITC conjugation of this monoclonal antibody allows for easy visualization and quantification of CD8a-positive cells through flow cytometry analysis, enabling researchers to characterize immune cell populations with precision and efficiency. With its reliable performance and suitability for mouse samples, this antibody is an essential tool for immunology studies, cancer research, and investigations into immune responses in various disease contexts.
Each lot of this antibody is quality control tested by flow cytometric analysis. Please check your vial before the experiment. Since applications vary, the appropriate dilutions must be determined for individual use. We suggest each investigator should titrate the reagent to obtain optimal results [The recommended concentration is 0.1-1 μg/106 cells in 100 μL volume].

Background:
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 34 kD 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.
