Flow Cytometry: F4/80 Antibody (CI:A3-1) [NBP2-61613]

Flow Cytometry: F4/80 Antibody (CI:A3-1) [NBP2-61613] - Figure 3 BMDMs were stained with Fc Silent recombinant anti-F4/80 or isotype control (Fc Silent anti-fluorescein [4-4-20 (enhanced)] IgG2b. These were fluorescently labelled using the secondary antibody, goat IgG anti-rat IgG (H&L-chain) polyclonal antibody directly conjugated to Alexa Fluor 647(AF647) commercially available from a competitor. The Fc silent format however overcomes this issue as seen in Figure 3, where the Fc silent recombinant anti-F4/80 yields a strong and distinct signal, whilst the isotype control shows no discernible difference to the background staining from the secondary antibody alone. Therefore, with Fc Silent reagents, no Fc-blocking products are required. [Data courtesy of Lewis Taylor.]

Background: F4/80

F4/80 antigen is a cell surface glycoprotein that is the murine homolog of human EGF-like module-containing mucin-like hormone receptor-like 1 (EMR1) (1,2). Specifically, F4/80 (EMR1) is one of five members belonging to the adhesion G-coupled receptor (ADGRE) subfamily, also known as the epidermal growth factor seven transmembrane (EGF-TM7) receptors (1,2). F4/80 is expressed by the myeloid lineage including in eosinophils, monocytes, macrophages, and myeloid dendritic cells (1,2). The molecular structure of F4/80 contains an EGF-like extracellular domain and a seven transmembrane motif, with a theoretical molecular weight of 160 kDa (1).

Depending on factors such as differentiation, activation, and location, the level of F4/80 expression can vary between cell-types (1,2). For example, peritoneal macrophages are subdivided based on morphology and expression with large peritoneal macrophages having high levels of F4/80 and small peritoneal macrophages having low F4/80 expression (1). Furthermore, splenic macrophages are classified based on location (red pulp, marginal zone, and white pulp) and F4/80 expression level varies within these populations as well; the red pulp macrophages have high levels of F4/80 and CD68 by comparison (1). Originally, the F4/80 monoclonal antibody was generated for a macrophage-specific surface antigen, however F4/80 staining is also observed in other hematopoietic cell populations, thus other immune cell markers should be used in conjunction with F4/80 to distinguish between different populations (1). Though the full extent of F4/80 ligands and biological functions remains elusive, studies have suggested that F4/80 is critical for macrophage-natural killer cell interaction and cytokine release (1,2). Additionally, a study of anterior chamber-associated immune deviation (ACAID) indicated a possible role for F4/80 in the generation of regulatory T cells (1,2).
