Options
Immunogen Crude thymus membrane fraction.
Clone MEM-31
Isotype IgG2a
Specificity 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.

HLDA III, WS Code T 575
Cross-Reactivity (Details) Human
Antigen
Background 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.
Application Notes The reagent is designed for Flow Cytometry analysis of human blood cells using 10 μ,l reagent / 100 μ,l of whole blood or 106 cells in a suspension.The content of a vial (1 ml) is sufficient for 100 tests.
Comment

The purified antibody is conjugated with cross-linked Allophycocyanin (APC) under optimum conditions. The conjugate is purified by size-exclusion chromatography and adjusted for direct use. No reconstitution is necessary.

Restrictions For Research Use only
Reconstitution No reconstitution is necessary.
Buffer The reagent is provided in stabilizing phosphate buffered saline (PBS) solution containing 15 mM sodium azide.
Preservative Sodium azide
Precaution of Use This product contains Sodium azide: a POISONOUS AND HAZARDOUS SUBSTANCE which should be handled by trained staff only.
Handling Advice Do not freeze.
Avoid prolonged exposure to light.
Storage 4 °C
Storage Comment Store in the dark at 2-8°C. Do not freeze. Avoid prolonged exposure to light. Do not use after expiration date stamped on vial label.
