Immunogen C91/PL (human HTLV-1+ T cell line)
Clone C33
Isotype IgG2a
Specificity The antibody C33 reacts with CD82, a widely expressed cell surface protein of the tetraspanin family. CD82 is also found in endosome/lysosome compartments.
Purification Purified from cell culture supernatant by protein-A affinity chromatography.
Purity > 95 % (by SDS-PAGE)
Alternative Name CD82
Background CD82 (KAI1), a member of the tetraspanin family, forms complexes with other tetraspanin proteins, integrins, coreceptors, MHC class I and II molecules. These complexes influence adhesion, morphology, activation, proliferation and differentiation of B, T and other cells. CD82 regulates cytoskeleton rearrangement and may participate in the turnover of the tetraspanin complex members. Besides in the plasma membrane, CD82 is localized also in endosome/lysosome compartments. Tumour-suppressive roles of CD82 have been demonstrated.
Gene ID 3732
Research Area Cancer, Transcription Factors, CD Antigens, Adaptive Immunity, Surface Receptors of Immune Cells
Application Notes Functional Application: In human MOLT-4 T-cell line the antibody C33 inhibits syncytium formation induced by coculture with human T-cell leukemia virus type 1 (HTLV-1)-positive human T-cell lines.

Restrictions For Research Use only
Concentration 1 mg/mL
Buffer Phosphate buffered saline (PBS) with 15 mM sodium azide, approx. pH 7.4
Preservative Sodium azide
Precaution of Use WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
Handling Advice Do not freeze.
Storage 4 °C
Storage Comment Store at 2-8 °C. Do not use after expiration date stamped on vial label.
