Application Notes:

Additional reported applications (for the relevant formats) include: immunohistochemical staining of acetone-fixed frozen sections1,2 and formalin-fixed paraffin-embedded sections6,7, and Western blotting.

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 ≤ 1.0 µg per 106 cells in 100 µl. For immunohistochemical staining on frozen tissue sections, the suggested use of this reagent is 2.5 - 10 µg/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.

Thioglycolate-elicited Balb/c mouse peritoneal macrophages

Thioglycolate-elicited Balb/c mouse peritoneal macrophages stained with BM8 Alexa Fluor® 488.

C57BL/6 mouse frozen spleen section

C57BL/6 mouse frozen spleen section was fixed with 4% paraformaldehyde (PFA) for ten minutes at room temperature and blocked with 5% FBS plus 5% rat/mouse serum for 30 minutes at room temperature. Then the section was stained with 5 µg/ml of anti-mouse F4/80 (clone BM8) Alexa Fluor® 488 (green), anti-mouse/human CD45R/B220 (clone RA3-6B2) Brilliant Violet 510™ (blue), and anti-mouse CD3 (clone 17A2) Brilliant Violet 421™ (red) overnight at 4°C. The image was captured with a 10X objective.



Description:

F4/80 is a 160 kD glycoprotein. It is characterized as a member of the epidermal growth factor (EGF)-transmembrane 7 (TM7) family. F4/80, also known as EMR1 or Ly71, has been widely used as a murine macrophage marker, which is expressed on the majority of tissue macrophages including peritoneal macrophages, macrophages in lung, gut, thymus and red pulp of spleen (but not on the macrophages located in T cell areas of the spleen, lymph node and Peyer's patch), Kuffer cells, Langerhans cells, and bone marrow stromal cells. F4/80 has also been shown on a subset of dendritic cells. The biological ligand of F4/80 has not been identified, but it has been reported that F4/80 is required for induction of CD8+ T cells-mediated peripheral tolerance.

Other Names: EMR1, Ly71

Distribution: Majority of tissue macrophages including peritoneal macrophages, macrophages in lung, gut, thymus and red pulp of spleen, Kuffer cells, Langerhans cells, bone marrow stromal cells, and a subset of dendritic cells
