CD11b (Cell Surface Glycoprotein MAC1 Alpha Subunit, Complement Component Receptor 3 Alpha, CR3A, ITGAM, MAC1A, MO1A, Neutrophil Adherence Receptor)

CD11b cell surface glycoprotein is a 165kD molecule also known as the alphaM integrin, MAC-1 and CR3. This molecule is expressed as a heterodimer in association with the beta 2 integrin, and is found upon monocytes, granulocytes, NK cells and some peripheral blood lymphocytes.\n\nApplications:\nSuitable for use in Flow Cytometry, Immunohistochemistry and Immunoprecipitation. Other applications not tested.\n\nRecommended Dilutions:\nFlow Cytometry: 1:10-1:100; 10ul labels 10e6 cells or 100ul whole blood.\nImmunohistochemistry (Frozen): 1:100-1000\nOptimal dilutions to be determined by the researcher.\n\nHybridoma: \nSp2/0 myeloma cells with spleen cells from Balb/c mice. \n\nPositive Control Tissue:\nHuman Tosil\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
