Description

FOXP3 is a 50-55 kD transcription factor, also known as Forkhead box protein P3, Scurfin, JM2, or IPEX. It is proposed to be a master regulatory gene and more specific marker of T regulatory cells than most cell surface markers (such as CD4 and CD25). Transduced expression of FOXP3 in CD4+/CD25- cells has been shown to induce GITR, CD103, and CTLA4 and impart a T regulatory cell phenotype. FOXP3 is mutated in X-linked autoimmunity-allergic dysregulation syndrome (XLAAD or IPEX) in humans and in "scurfy" mice. Overexpression of FOXP3 has been shown to lead to a hypoactive immune state suggesting that this transcriptional factor is a central regulator of T cell activity. In human, unlike in mouse, two isoforms of FOXP3 have been reported: one (FOXP3) corresponding to the canonical full-length sequence; the other (FOXP3 δ2) lacking exon 2. The 259D antibody recognizes human FOXP3 epitope in the region of amino acids 105-235.

Application Notes

Materials Provided:
1. Alexa Fluor® 488 anti-human FOXP3 - 25 tests
2. Alexa Fluor® 488 Mouse IgG1, κ isotype control - 25 tests
3. True-Nuclear™ Transcription Factor Buffer Set - 120 tests (Cat. No. 424401)
4. anti-human CD4 PE-Cyn5/CD25 PE Cocktail - 50 tests

Materials Not Included:
1. Cell Staining Buffer (Cat. No. 420201)
2. Single color compensation controls

Immunofluorescence Staining Procedures:
1. Perform cell surface staining as described in BioLegend's Cell Surface Immunofluorescence Staining Protocol. Add 20 µL of the anti-human CD4 PE-Cyn5/CD25 PE cocktail to each tube and incubate in the dark for 20 minutes.
2. Add 2 mL of the cell staining buffer, centrifuge tubes at 400 x g at room temperature for five minutes, and discard the supernatant.
3. Repeat Step 2, for a total of two washes.
4. Add 1 mL of the Transcription Factor 1X Fix solution to each tube, vortex, and incubate at room temperature in the dark for 45-60 minutes.
5. Without washing, add 2 mL of the Transcription Factor 1X Perm Buffer to each tube.
6. Centrifuge tubes at 400 x g at room temperature for five minutes, and discard the supernatant.
7. Add 2 mL of the Transcription Factor 1X Perm Buffer to each tube.
8. Centrifuge tubes at 400 x g at room temperature for five minutes, and discard the supernatant.
9. Resuspend the cell pellet in 100 µL of the Transcription Factor 1XPerm Buffer.
10. Add 5 µL of Alexa Fluor® 488 anti-human FOXP3 antibody or 5 µL of Alexa Fluor® 488 mouse IgG1, κ isotype control into the appropriate tubes. Incubate in the dark at room temperature for at least 30 minutes.
11. Add 2 mL of the Transcription Factor 1X Perm Buffer to each tube.
12. Centrifuge tubes at 400 x g at room temperature for five minutes, and discard the supernatant.
13. Add 2 mL of the cell staining buffer.
14. Centrifuge tubes at 400 x g at room temperature for five minutes, and discard the supernatant.
15. Resuspend in 0.5 mL cell staining buffer and then acquire tubes on a flow cytometer.

Caution: The True-Nuclear™ Transcription Factor Buffer Set contains paraformaldehyde, which is toxic and mutagenic. Please handle with caution. Wear gloves, lab coats, and necessary protection to avoid direct contact.

NOTE: For flow cytometric staining with this clone, True-Nuclear™ Transcription Factor Buffer Set (Cat. No. 424401) offers improved staining and is highly recommended.

Can I stain whole blood with anti-FOXP3 using your Foxp3 staining kit?

It is not recommended. It is best to use PBMCs for this testing.
