Description

CD8α, also known as T8 or Leu2, is a 32-34 kD type 1 transmembrane glycoprotein part of the immunoglobulin superfamily. CD8α is expressed on cytotoxic T cells, NK cells, as well as a majority of thymocytes. CD8α can form a homodimer (CD8α/α) or heterodimer (CD8α/β) with CD8β. CD8α acts as a co-receptor with MHC class I-restricted T cell receptors in antigen recognition and T cell activation, and has been shown to play a role in thymic differentiation. Two domains in CD8α are important for function: the extracellular Ig superfamily domain binds the α3 domain of MHC Class I and the cytoplasmic CXCP motif binds the tyrosine kinase p56 Lck.

Application

FC - Quality tested
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

Clone S21010A can completely block the binding of clone HIT8a on target cells and can be blocked by HIT8a. Clone S21010A does not block the binding of clone SK1, clone RPA-T8, and clone S21010F.

Clone S21010A does not interfere with the binding of anti-human CD8β antibodies S21011A or QA20A40.

Clone S21010A shows comparable staining signals on 4% paraformaldehyde-fixed cells and unfixed cells.
