설명
The FoxP3 Staining Kit - Alexa Fluor® 647, FoxP3, CD4, CD25 provides cellular fixation and permeabilization buffers and fluorescent antibodies that specifically bind to human FoxP3, CD4 and CD25. The kit enables multicolor staining and flow cytometric analysis of human cells for their patterns of cell surface CD4 and CD25 and intracellular FoxP3 expression. The kit includes Alexa Fluor® 647 Mouse anti-Human FoxP3 (Cat No. 560045) antibody that specifically binds to all currently identified isoforms of the human FoxP3 transcription factor, a member of the forkhead or winged helix family of transcription factors. The expression of FoxP3, also known as Scurfin, IPEX and JM2, has been found to be associated with CD4+ regulatory T cells and represents a specific marker for these cells. Flow cytometric analysis has shown that FoxP3 is expressed by the majority of CD4+CD25+high T cells in peripheral blood while less than half of CD4+CD25int cell population are FoxP3 positive. Approximately 5-10% of peripheral CD4+ cells are CD4+CD25+ T regulatory cells. T regulatory cells are thought to play a critical role in the control of T cell mediated autoimmunity by suppressing the proliferation and cytokine production of other T cells. To support this hypothesis, it has been found that Foxp3 is mutated in scurfy (sf) mice.

Cell Preparation and Staining Procedures for Conjugated Anti-Human FoxP3 Antibody
1. Bring the buffers to room temperature (RT) before use. Prepare working solutions of the BD Pharmingen™ Human FoxP3 Buffer Set Cat. No. 560098 (For the buffer preparation, please see TDS Cat. No. 560098 buffer instructions for details).
2. Prepare a suspension of human peripheral blood mononuclear cells. Suspend the cells with BD Pharmingen Stain Buffer (FBS) (Cat. No. 554656)* to ten million cells/ml.
3. Pipet appropriate amount of surface staining reagent to bottom of each 12 x 75 mm tube.
4. Add 100 µ l of cells per tube, vortex, incubate for 20 minutes at RT protected from light.
5. Add 2 ml of wash buffer. Centrifuge 250g for 10 minutes, and remove wash buffer.
6. To fix the cells, gently resuspend the cell pellet in residual volume of wash buffer and then add 2 ml of 1x Human FoxP3 Buffer A. Vortex.
Incubate for 10 minutes at RT in the dark.
7. Centrifuge 500g for 5 minutes and remove fixative. Caution: Be aware the cell pellet is buoyant.
8. To wash cells, resuspend each cell pellet in 2 ml of BD Pharmingen Stain Buffer (FBS)*, and
