Immunogen Leukocytes from a pacient suffering from a LGL-type leukaemia.
Clone MEM-25
Isotype IgG1
Specificity The antibody MEM-25 reacts with CD11a (alpha subunit of human LFA-1), a 170-180 kDa type I transmembrane glycoprotein expressed on B and T lymphocytes, monocytes, macrophages, neutrophils, basophils and eosinophils. HLDA IV, WS Code NL 209
Purification Purified from ascites by protein-A affinity chromatography.
Purity > 95 % (by SDS-PAGE)
Alternative Name ITGAL (ITGAL Antibody Abstract)
Background CD11a (LFA-1 alpha) together with CD18 constitute leukocyte function-associated antigen 1 (LFA-1), the alphaLbeta2 integrin. CD11a is implicated in activation of LFA-1 complex. LFA-1 is expressed on the plasma membrane of leukocytes in a low-affinity conformation. Cell stimulation by chemokines or other signals leads to induction the high-affinity conformation, which supports tight binding of LFA-1 to its ligands, the intercellular adhesion molecules ICAM-1, -2, -3. LFA-1 is thus involved in interaction of various immune cells and in their tissue-specific settlement, but participates also in control of cell differentiation and proliferation and of T-cell effector functions. Blocking of LFA-1 function by specific antibodies or small molecules has become an important therapeutic approach in treatment of multiple inflammatory diseases. For example, humanized anti-LFA-1 antibody Efalizumab (Raptiva) is being used to interfere with T cell migration to sites of inflammation, binding of cholesterol-lowering drug simvastatin to CD11a allosteric site leads to immunomodulation and increase in lymphocytic cholinergic activity.
Research Area Stem Cells, Hematopoietic Progenitors, CD Antigens, Surface Receptors of Immune Cells
Application Notes Flow Cytometry: Recommended dilution: 2 µg/mL
Immunoprecipitation: excellent antibody for immunoaffinity purification of LFA-1 complex
Functional Application: The antibody MEM-25 partially blocks binding of LFA-1 complex to ICAM-1.

Working concentrations should be determined by the investigator.
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.
