BV421 Rat Anti-Mouse Foxp3
BV421 Rat Anti-Mouse Foxp3

Multicolor flow cytometric analysis of Foxp3 expression in BALB/c mouse splenocytes. Splenic leucocytes from BALB/c mice were stained with APC Rat anti-Mouse CD4 antibody (Cat. No. 553051/561091), and fixed and permeabilized using working solutions of the BD Pharmingen™ Transcription Factor Buffer Set (Cat. No. 562574/562725). The cells were then stained with BD Horizon™ BV421Rat Anti-Mouse Foxp3 antibody (Cat. No. 562996). The flow cytometric dot plot shows the correlated expression of Foxp3 versus CD4 for gated events with the forward and side light-scattering characteristics of intact leucocytes. Flow cytometry was performed using a BD LSRFortessa™ Cell Analyzer System.

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 BD Horizon BV421 under optimum conditions, and unconjugated antibody and free BD Horizon BV421 were removed.

MF-23

The MF23 monoclonal antibody specifically binds to mouse Foxp3. Foxp3 is a 50-55 kDa protein also known as Forkhead box p3, JM2, or IPEX. It is a member of the forkhead or winged helix family of transcription factors and is specifically expressed by T regulatory (Treg) cells. Foxp3 has been reported to be 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. Immunoblotting with MF23 antibody has confirmed it recognizes an epitope between 1-87 amino acids in the N-terminal domain.

The antibody was conjugated to BD Horizon™ BV421 which is part of the BD Horizon™ Brilliant Violet™ family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon™ BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon™ BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue™ conjugates.

BV421
The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
