Specifications

Application	FC
Article No	AFC-51E0LG-100
Biosite Brand	Biosite Flow
Country Availability	all
Clone	MEM-31
Clone Type	monoclonal
Conjugation	PE/Cy7
Description	Anti-Hu CD8 PE-Cy™7
Supplier	Nordic Biosite
Format	PE-Cy7
Immunogen	Crude thymus membrane fraction.
Isotype	IgG2a
Notes	The CD8 T cell coreceptor (monomer approx. 32-34 kDa) is expressed as alpha/beta heterodimer on majority of MHC I-restricted conventional T cells and thymocytes and as alpha/alpha homodimer on subsets of memory T cells, intraepithelial lymphocytes, NK cells and dendritic cells. Regulation of CD8 beta level on T cell surface seems to be an important mechanism to control their effector function. Assembly of CD8 alpha-beta but not alpha-alpha dimers is connected with formation or localization to the lipid rafts. Recruiting triggered TCR complexes to these membrane microdomains as well as affinity of TCR to MHC I is modulated by CD8, thereby affecting the functional diversity of the TCR signaling.
Alias Names	p32, LEU2
Product Type	Antibodies Primary
Protocol	Flow cytometry: The reagent is designed for analysis of human blood cells using 4 μl reagent / 100 μl of whole blood or 106 cells in a suspension. The content of a vial (0.4 ml) is sufficient for 100 tests.
Purification	Purified antibody is conjugated with activated tandem dye of R-phycoerythrin-cyanine 7 (PE-Cy™7) under optimum conditions and unconjugated antibody and free fluorochrome are removed by size-exclusion chromatography.
Size	100 tests
Source / Host	mouse
Species Reactivity	human
Storage	Store at 2-8°C. Protect from prolonged exposure to light. Do not freeze.
Substrate / Buffer	Stabilizing phosphate buffered saline (PBS), pH 7.4, 15 mM sodium azide
Technical Specifications	The antibody MEM-31 recognizes a conformationally-dependent epitope of CD8, a cell surface glycoprotein found on most cytotoxic T lymphocytes that mediates efficient cell-cell interactions within the immune system. CD8 is a disulfide-linked dimer and exists as a CD8 alpha/alpha homodimer or CD8 alpha/beta heterodimer (each monomer approx. 32-34 kDa). The antibody does not react with formaldehyde-fixed cells; negative in Western blotting application.
