CD8A Mouse Monoclonal Antibody [Clone ID: MEM-31]

Specifications

Product Data
Clone Name	MEM-31
Applications	FC
Recommend Dilution	Flow Cytometry analysis of human blood cells using 10 μl reagent / 100 μl of whole blood or 106 cells in a suspension. The content of a vial (1 ml) is sufficient for 100 tests. The antibody does not react with formaldehyde-fixed cells; negative in Western Blotting application.
Reactivity	Human
Host	Mouse
Clonality	Monoclonal
Immunogen	Crude thymus membrane fraction
Specificity	This antibody 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 CD8α homodimer or CD8α/β heterodimer (each monomer approx. 32-34 kDa).
Formulation	Phosphate buffered saline (PBS) solution containing 15mM sodium azide Label: APC State: Liquid Ig fraction Label: Conjugated with cross-linked Allophycocyanin under optimum conditions. The conjugate is purified by size-exclusion chromatography and adjusted for direct use.
Conjugation	APC
Storage Condition	Store the antibody at 2 - 8 °C. DO NOT FREEZE! This product is photosensitive and should be protected from light.
Gene Name	CD8a molecule
Database Link	Entrez Gene 925 Human UniProt ID P01732
Background	The CD8 T cell coreceptor (monomer approx. 32-34 kDa) is expressed as αβ heterodimer on majority of MHC I-restricted conventional T cells and thymocytes and as αα homodimer on subsets of memory T cells, intraepithelial lymphocytes, NK cells and dendritic cells. Regulation of CD8β level on T cell surface seems to be an important mechanism to control their effector function. Assembly of CD8 α-β but not α-α 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.
Synonyms	CD8 alpha chain, CD8A, MAL
