CD11b is a 170 kD glycoprotein also known as αM integrin, Mac-1 α subunit, Mol, CR3, and Ly-40. CD11b is a member of the integrin family, primarily expressed on granulocytes, monocytes/macrophages, dendritic cells, NK cells, and subsets of T and B cells. CD11b non-covalently associates with CD18 (β2 integrin) to form Mac-1. Mac-1 plays an important role in cell-cell interaction by binding its ligands ICAM-1 (CD54), ICAM-2 (CD102), ICAM-4 (CD242), iC3b, and fibrinogen.Product Details

FC - Quality tested
IHC-F - Validated
- Recommended Usage
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per 106 cells in 100 µl volume. For immunohistochemical staining on frozen tissue sections, the suggested use of this reagent is 2.5 - 10 µg per ml. It is recommended that the reagent be titrated for optimal performance for each application.
* Alexa Fluor® 488 has a maximum emission of 519 nm when it is excited at 488 nm.

- Application Notes
Clone M1/70 has been validated for immunocytochemistry (ICC) and frozen immunohistochemistry (IHC-F).
Additional reported applications (for relevant formats of this clone) include: immunoprecipitation1,4, in vitro blocking3,9,12, depletion2,8, immunofluorescence microscopy6,7,10, and immunohistochemistry of acetone-fixed frozen sections5,11-13 and paraffin sections28. The LEAF™ purified antibody (Endotoxin <0.1 EU/μg, Azide-Free, 0.2 μm filtered) is recommended for functional assays (Cat. No. 101231). For in vivo studies or highly sensitive assays, we recommend Ultra-LEAF™ purified antibody (Cat. No. 101248) with a lower endotoxin limit than standard LEAF™ purified antibodies (Endotoxin <0.01 EU/µg).
