CD8 Antibody (MHCD0804) in Flow

Dual color flow cytometry dot plot showing mouse anti human CD8 RPE vs. mouse anti human CD4 biotin followed by streptavidin RPE-Alexa Fluor® 610. Human mononuclear cells were stained with mouse anti human CD4 biotin (Product # MHCD0415), washed, stained with streptavidin RPE-Alexa Fluor® 610 (Product # S-20982) and mouse anti human CD8 RPE (Product # MHCD0804), washed, and analyzed on a flow cytometer with a 488 nm excitation source.

产品详细信息

R-phycoerythrin (PE) is a stable and highly soluble phycobiliprotein which provides maximal absorbance and fluorescence without susceptibility to internal or external fluorescence quenching, thus providing an exceptional quantum yields and molar extinction coefficients.

靶标信息

Cluster of differentiation 8 (CD8), a type I transmembrane glycoprotein of the immunoglobulin family of receptors, plays an integral role in signal transduction, and T cell differentiation and activation. CD8 is predominantly expressed on T cells as a disulfide-linked heterodimer of CD8alpha and CD8beta, where it functions as a co-receptor, along with T cell receptor (TCR), for major histocompatibilty complex class I (MHC-I) molecules; whereas its counterpart, CD4, acts as a co-receptor for MHC-II molecules. CD8 exists on the cell surface, where the CD8alpha chain is essential for binding to MHC-I. CD8 is also expressed on a subset of T cells, NK cells, monocytes and dendritic cells as disulfide-linked homodimers of CD8alpha. Ligation of MHC-I/peptide complexes presented by antigen-presenting cells (APCs), triggers the recruitment of lymphocyte-specific protein tyrosine kinase (Lck), which leads to lymphokine production, motility and cytotoxic T lymphocyte (CTL) activation. Once activated, CTLs play a crucial role in the clearance of pathogens and tumor cells. Differentiation of naive CD8+ T cells into CTLs is strongly enhanced by IL-2, IL-12 and TGF-beta1.

MHCD0804 was used in Flow cytometry/Cell sorting to identify significant interactions that support a model in which a) IFNα increases the proportion of pro-inflammatory, bisecting GlcNAc glycans (known to enhance FcγR binding) within the IgG glycome, which in turn b) increases inflammation, which c) leads to poor CD8+ T cell phenotypes and poor IFNα-mediated reduction of HIV DNA.
