A. Solutions and Reagents

NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.

  1. 20X Phosphate Buffered Saline (PBS): (#9808) To prepare 1 L 1X PBS: add 50 ml 20X PBS to 950 ml dH2O, mix.
  2. Incubation Buffer: Dissolve 0.5 g Bovine Serum Albumin (BSA) (#9998) in 100 ml 1X PBS. Store at 4°C.

B. Immunostaining

  1. Count cells using a hemacytometer or alternative method.
  2. Aliquot 0.5-1x106 cells into each assay tube (by volume).
  3. Add 2-3 ml Incubation Buffer to each tube and rinse by centrifugation. Repeat.
  4. Resuspend cells in 100 µl of diluted primary antibody (prepared in incubation buffer at the recommended dilution).
  5. Incubate for 1 hr at room temperature.
  6. Wash by centrifugation in 2-3 ml incubation buffer.
  7. Resuspend cells in the appropriate volume of PBS and analyze on flow cytometer.

F4/80 (BM8.1) Rat mAb (PE-Cy7® Conjugate) recognizes endogenous levels of total F4/80 protein. This antibody detects an epitope within the extracellular domain.

Species Reactivity:


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.

This Cell Signaling Technology antibody is conjugated to PE-Cy7® and tested in-house for direct flow cytometric analysis in mouse cells.

F4/80 (EMR1) is a heavily glycosylated G-protein-coupled receptor and is a well-established marker for mouse macrophages (1-3).

BM8.1 is widely used together with antibodies to CD115 (c-Fms), CD11b, and CD11c to identify myeloid/macrophage cells by flow cytometry.
