Two-color flow cytometric analyses of F4/80 expression. The two-color flow cytometric contour plots showing the correlated expression of F4/80 (or Ig Isotype control staining) versus CD11b (Mouse Splenocytes; Top Plots) or CD117 (Mouse Peritoneal Exudate Cells; Bottom Plots) were derived from gated events with the forward and side light-scatter characteristics of viable (7-AAD-negative) monocytes. Flow cytometric analyses were performed using a BD LSRFortessa™ Cell Analyzer System. Data shown on this Technical Data Sheet are not lot specific. Top Plots - Mouse splenocytes. C57BL/6 mouse splenic leucocytes were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) (Cat. No. 553141/553142) and stained with FITC Rat Anti- CD11b antibody (Cat. No. 553310/557396/561688) and either BD Horizon™ APC-R700 Rat IgG2a Isotype Control (Cat. No. 564982; Left Plot) or BD Horizon APC-R700 Rat Anti-Mouse F4/80 antibody (Cat. No. 565787; Right Plot) at 0.5 µg/test. BD Via-Probe™ Cell Viability 7-AAD Solution (Cat. No. 555815/555816) was added to cells right before analysis. Bottom Plots - Mouse peritoneal exudate cells (PEC). C57BL/6 mouse PEC were similarly pretreated with Mouse BD Fc Block™, stained with FITC Rat Anti-Mouse CD117 antibody (Cat. No. 553354/561680) and either BD Horizon™ APC-R700 Rat IgG2a Isotype Control (Left Plot) or BD Horizon APC-R700 Rat Anti-Mouse F4/80 antibody (Right Plot) at 0.5 µg/test flowed by BD Via-Probe™ Cell Viability 7-AAD Solution, and analyzed.

Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

The T45-2342 monoclonal antibody recognizes the mouse F4/80 antigen which is also known as EGF-like module-containing mucin-like hormone receptor-like 1 (EMR1). F4/80 is a 160 kDa glycoprotein that belongs to the EGF-TM7 family of seven-transmembrane spanning cell surface molecules. It is expressed on the surface of granulocytes and a wide range of mature tissue macrophages including, Kupffer cells, splenic red pulp macrophages, microglia, gut lamina propria macrophages, and Langerhans cells. F4/80 expression has also been reported on subpopulations of dendritic cells. F4/80 expression is heterogeneous and may be increased during inflammatory responses as observed in various mouse models of colitis, diabetes and brain injury.
This antibody was conjugated to BD Horizon APC-R700, which has been developed exclusively by BD Biosciences as a better alternative to Alexa Fluor® 700. APC-R700 excites and emits at similar wavelengths to Alexa Fluor® 700 yet exhibits significantly improved brightness. This dye can be excited by the red laser and detected with the same filter set as Alexa Fluor® (eg, 730/45-nm filter).
