Specifications

Application	FC
Article No	AFC-AR630K-100
Biosite Brand	Biosite Flow
Country Availability	all
Clone	MEM-31
Clone Type	monoclonal
Conjugation	PE
Description	Anti-Hu CD8 PE
Recommended Dilution	The purified antibody is conjugated with R-Phycoerythrin (PE) under optimum conditions. The conjugate is purified by size-exclusion chromatography and adjusted for direct use. No reconstitution is necessary.
Supplier	Nordic Biosite
Format	PE
Immunogen	Crude thymus membrane fraction.
Isotype	IgG2a
Keywords	CD and Related Antigens (Human)
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
Previous Article No	AFC-5112-2
Product Type	Antibodies Primary
Protocol	Flow cytometry: The reagent is designed for analysis of human blood cells using 20 μl reagent / 100 μl of whole blood or 106 cells in a suspension. The content of a vial (2 ml) is sufficient for 100 tests.
Purification	Purified antibody is conjugated with R-phycoerythrin (PE) under optimum conditions. Unconjugated antibody and free fluorochrome are removed by size-exclusion chromatography.
Research area	Immunology
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 extracellular 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.
