This Cell Signaling Technology antibody is conjugated to APC-Cy7® and tested in-house for direct flow cytometric analysis in mouse cells.
For optimal flow cytometry results, we recommend 0.125 μg of antibody per test.
Supplied in 10 mM NaH2PO4, 150 mM NaCl, 0.09% NaN3, 0.1% gelatin, pH 7.2. This product is stable for 6 months when stored at 4ºC. Do not aliquot the antibody. Protect from light. Do not freeze.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
NOTE: When including fluorescent cellular dyes in your experiment (including viability dyes, DNA dyes, etc.), please refer to the dye product page for the recommended protocol. Visit www.cellsignal.com for a full listing of cellular dyes validated for use in flow cytometry.
NOTE: Count cells using a hemocytometer or alternative method.
NOTE: If using whole blood, lyse red blood cells and wash by centrifugation prior to Immunostaining.
NOTE: Optimal centrifugation conditions will vary depending upon cell type and reagent volume. Generally, 150-300g for 1-5 minutes will be sufficient to pellet the cells.

CD11b/ITGAM (M1/70) Rat mAb (APC-Cy7® Conjugate) recognizes endogenous levels of total CD11b protein. This antibody detects an epitope within the extracellular domain.
This monoclonal antibody was purified from tissue culture supernatant via affinity chromatography. The purified antibody was conjugated under optimal conditions, with unreacted dye removed from the preparation.
Cluster of differentiation molecule 11b (CD11b)/Integrin alpha M (ITGAM) is a transmembrane protein forming heterodimers that are composed of α and β subunits (1). CD11b is expressed by, and commonly used as a marker for, myeloid lineage cells, including neutrophils, monocytes, macrophages, and microglia (2). CD11b is phosphorylated at Ser1126 (cytoplasmic tail) in neutrophils. Research has shown that this phosphorylation event plays a role for leukocytes traveling from the blood stream to tissues (3). Furthermore, genome-wide association studies have linked CD11b to autoimmune diseases, such as systemic lupus erythematous (SLE) (4).
The M1/70 antibody is widely used as a marker for CD11b expression on neutrophils, macrophages, NK cells, and dendritic cells (DC) (5,6).
