FC - Quality tested

Application Notes:

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.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining using the µg size, the suggested use of this reagent is ≤0.25 µg per million cells in 100 µl volume. For flow cytometric staining using the µl size, the suggested use of this reagent is ≤5 µl per million cells or 5 µl per 100 µl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.

Brilliant Violet 605™ excites at 405 nm and emits at 603 nm. The bandpass filter 610/20 nm is recommended for detection, although filter optimization may be required depending on other fluorophores used. Be sure to verify that your cytometer configuration and software setup are appropriate for detecting this channel. Refer to your instrument manual or manufacturer for support.

C57BL/6 mouse bone marrow cells

C57BL/6 mouse bone marrow cells were stained with CD11b (clone M1/70) Brilliant Violet 605™. Data shown was gated on myeloid cell population.


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.

Other Names: αM integrin, Mac-1, Mo1, CR3, Ly-40, C3biR, ITGAM
Structure: Integrin family, associates with integrin β2 (CD18), 170 kD
Distribution: Granulocytes, monocytes/macrophages, dendritic cells, NK cells, subsets of T and B cells
Function: Adhesion, chemotaxis
Ligand Receptor: ICAM-1 (CD54), ICAM-2 (CD102), ICAM-4 (CD242), iC3b, fibrinogen
