Product Overview
This rabbit polyclonal antibody recognizes integrin alpha-M (gene Itgam) in mouse samples and is validated for Western blot. The predicted molecular weight is 127.5 kDa, and the supplier reports an observed band at about 128 kDa.
Integrin alpha-M (ITGAM, CD11b) pairs with integrin beta-2 to form Mac-1, also called complement receptor 3. It binds the complement fragment iC3b, fibrinogen and ICAM-1, supporting adhesion, migration and phagocytosis by monocytes, macrophages and neutrophils. CD11b is one of the most widely used myeloid cell markers.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Mouse) |
|---|
Samples with a confirmed band (WB): mouse brain tissue, HEPA cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 50 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:10000, ECL detection.
Immunogen
Recombinant mouse CD11b fragment (Glu260–Thr360), expressed in E. coli. Sequence identity with the human ortholog: 82.2%.
Reactivity Notes
The supplier lists reactivity with mouse. UniProt places integrin alpha-M in the cell membrane and membrane raft. Tissue expression noted by UniProt (mouse): Predominantly expressed in monocytes and granulocytes. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
