Multicolor flow cytometric analysis of Foxp3 expression in mouse splenocytes. C57BL/6 mouse spleen cells were treated with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899) to lyse erythrocytes. The leucocytes were washed, fixed and permeabilized using the Transcription Factor Buffer Set (Cat. No. 562574/562725). The cells were then stained with BD Horizon™ BV421 Rat Anti-Mouse CD4 antibody (Cat. No. 562891), APC Rat Anti-Mouse CD25 antibody (Cat. No. 557192) and either PE Mouse IgG1, κ Isotype Control (Cat. No. 554680; Top Plots) or PE Mouse Anti-Foxp3 antibody (Cat. No. 566881; Bottom plots) at 0.125 µg/test. Left Plots: Two-color flow cytometric dot plots showing the correlated expression of CD4 versus Foxp3 (or Ig Isotype control staining) were derived from gated events with the forward and side light-scatter characteristics of intact cells. Right Plots: Two-color flow cytometric dot plots showing the correlated expression of Foxp3 (or Ig Isotype control staining) versus CD25 were derived from CD4 positive-gated events with the light-scatter characteristics of intact cells. Flow cytometric analysis was performed using a BD LSRFortessa™ X-20 Flow Cytometer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.

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.

3G3

The 3G3 monoclonal antibody specifically binds to Forkhead box protein P3 (Foxp3) which is also known as Scurfin and JM2. Foxp3 is a 50-55 kDa protein that is encoded by Foxp3 (forkhead box P3) which belongs to the forkhead/winged helix family of transcriptional regulators. FoxP3 contains a single C2H2-type zinc-finger motif, a leucine-zipper region, and a C-terminal forkhead DNA-binding domain. Foxp3 is expressed by natural (nTreg) and induced/adaptive (iTreg) T regulatory cells. Foxp3 is a key transcription factor for Treg cell development and regulatory function. Treg cells play crucial roles in maintaining immune homeostasis by enforcing immunological tolerance to self-antigens and by suppressing excessive responses made by other immune cells to foreign antigens. Ectopic expression of Foxp3 in conventional T cells is sufficient to induce suppressive activity, repress the production of cytokines such as IL2 and IFN-γ, and upregulate Treg cell-associated molecules such as CTLA4/CD152 and GITR/TNFRSF18. A mutation in Foxp3 causes a lack of functional Tregs in Scurfy (sf) mice which develop a systemic disease state with autoimmune manifestations. The 3G3 antibody reportedly binds to the N-terminus of Foxp3.

Format Details

R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Format: PE

Excitation Source: Yellow-Green 488 nm, 532 nm, 561 nm
