Clone: M1-70

Description: M subunit (Mr 170 kDa) of the CD11b/CD18 heterodimer CD11b, the integrin M subunit, combines with CD18, the integrin 2 subunit, to form the integrin Mac-1, also known as complement receptor 3 (CR3), which mediates adhesion to C3bi and ICAM-1/CD54.2, 3 Mac-1 is expressed at varying levels on granulocytes, macrophages, dendritic cells, NK cells, and B-1 cells in the peritoneal and pleural cavities.2-8 Mac-1 expression is rapidly up-regulated on neutrophils after activation and in the same time period that CD62L is shed from the cell surface. In addition to its role in binding C3bi on opsonized targets and mediation of the subsequent ingestion process, Mac-1 is important as an adhesion molecule in the transendothelial migration of monocytes and neutrophils.4, 9, 10 Cross-reaction of M1/70 to human CD11b has been observed on monocytes, polymorphonuclear leukocytes, and NK cells.4,

Application Details

Application Notes: Working Dilutions: Flow Cytometry: Purified (1 ug/10^6 cells), Fluorescein (1 ug/10^6 cells), Biotin (1 ug/10^6 cells), Phycoerythrin (0.3 ug/10^6 cells), Allophycocyanin (0.3 ug/10^6 cells), Spectral RedTM (0.3 ug/10^6 cells), Cyanine 5 (0.3 ug/10^6 cells), R-phycoerythrin-Cyanine 7 (0.3 ug/10^6 cells), Allophycocyanin-Cyanine 7 (0.3 ug/10^6 cells). Since applications vary, you should determine the optimum working dilution of the product that is appropriate for your specific need.

Store at 2-8C. Do not freeze! The low endotoxin, azide-free (LE/AF) antibody is supplied as 0.5 mg purified immunoglobulin in 1.0 mL of PBS. Aliquot and store at or below -20C. The Cyanine 5 (CYTM5) conjugate is supplied as 0.1 mg in 1.0 mL of PBS/NaN3. Store at 2-8C. Protect conjugated forms from light. Aliquot and freeze the low endotoxin, azide-free product at -20C immediately upon receipt. Each reagent is stable for the period shown on the bottle label if stored as directed. 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.
