Alexa Fluor® 647 Rat Anti-Mouse Foxp3
Alexa Fluor® 647 Rat Anti-Mouse Foxp3

Two-color flow cytometric analysis of Foxp3 expression in mouse splenocytes. Mouse splenic leucocytes were fixed and permeabilized using appropriately-diluted solutions from the Transcription Factor Buffer Set (Cat. No. 562574/562725). The cells were then stained with FITC Rat Anti-Mouse CD4 (Cat. No. 553047/553046/561835) and Alexa Fluor® 647 Rat Anti-Mouse Foxp3 (Cat. No. 563486) antibodies. The two-color flow cytometric dot plot shows the correlated expression patterns of CD4 versus Foxp3 for gated events with the forward and side light-scatter characteristics of intact lymphocytes. Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer System.

Multicolor flow cytometric analysis of Foxp3 expression in mouse splenic lymphocytes. BALB/c mouse splenic leucocytes were fixed and permeabilized using Transcription Factor Buffer Set (Cat. No. 562574/562725). The cells were then stained with PE Rat Anti-Mouse CD4 (Cat. No. 553048/553049/561837) either Alexa Fluor™ 647 Rat IgG2a, κ Isotype Control (Cat. No. 557690; Left Plot) or Alexa Fluor™ 647 Rat Anti-Mouse Foxp3 antibody (Cat. No. 563486; Right Plot) at 0.06 µg/test. The bivariate pseudocolor density plots show the correlated expression patterns of CD4 versus Foxp3 (or Ig Isotype control staining) for gated events with the forward and side light-scatter characteristics of intact lymphocytes. Flow cytometry and data analysis was performed using a BD LSRFortessa™ Cell Analyzer System and FloJo™ software. Data 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 to the dye under optimum conditions and unreacted dye was removed.

Recommended Assay Procedures

BD® CompBeads can be used as surrogates to assess fluorescence spillover (Compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells.  However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. 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.
  4. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  5. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).

R16-715

The R16-715 monoclonal antibody specifically binds to mouse Foxp3. Foxp3 is a 50-55 kDa protein also known as Forkhead box P3, JM2, IPEX, Scurfin, and  Sf. It is a member of the forkhead or winged helix family of transcription factors and is specifically expressed by T regulatory (Treg) cells. Foxp3 is a key regulatory protein for Treg cell development and function. 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 CD25, CTLA4 and GITR. It has been found that the mutation of Foxp3 is responsible for "scurfy" mice. When overexpressed, Foxp3 leads to poor T cell proliferation and activation.

Alexa Fluor™ 647
Alexa Fluor™ 647 Dye is part of the BD red family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 653-nm and an emission maximum (Em Max) at 669-nm. Alexa Fluor 647 is designed to be excited by the Red laser (627-640 nm) and detected using an optical filter centered near 520-nm (e.g., a 660/20 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
