Background

One of the many immunotolerance mechanisms that the immune system has developed to distinguish between self and non-self antigens is regulatory T cells or Tregs. Several elegant experiments using transgenic mice and retrovirus-mediated over expression studies, have led to the identification of FoxP3, a transcription factor, as a specific molecular marker essential for the development and function of Tregs. The primary evidence regarding the involvement of FoxP3 in the development of Tregs was provided in patients suffering from IPEX, a rare and fatal human autoimmune disease. The emergence of Tregs and the role of FoxP3 as a critical player in the negative control of various normal and pathological immune responses holds great promise for the development of novel therapies for autoimmune diseases.

FAQs for FoxP3 Antibody (NB100-56582). (Showing 1 - 4 of 4 FAQs).

1. Does FoxP3 antibodies comes in lyophilized form?
   • FoxP3 antibodies, aka JM2 IPEX, and Scurfin antibodies, have the following products in lyophilized form: NBP1-18319, AF3240.
2. What the theoretical molecular weight for FoxP3 antibodies?
   • The TMW of FoxP3 antibodies is approximately 47 - 52 kDa.
3. Since the protocol to isolate cells from mice seems to be quite long I would like to know if you have experience in staining with Foxp3 and Ror gamma and leaving cells overnight? Would you suggest leaving cells overnight in Fix/Perm or better after having completed the staining? And in which buffer would you leave them then?
   • Where as FOXP3 and ROR gamma staining can be stopped after the fixation step, we suggest that researchers strictly follow the protocol without variation (even if it takes a long time), when trying for the 1st time. After you establish this for your system, then you can work on optimizing a varied protocol according to your needs and convenience. In this case, after the fix/perm step (Step 13 of NBP2-266911) wash the cells in 1X Staining buffer (2 times) and suspend in Staining buffer (500 ul) overnight. Then, in the morning proceed to Step 14 and continue the protocol.
4. What is the immunogen sequence of this FoxP3 antibody?
   • The full-length His-tagged murine FOXP3 was used as the immunogen.  The precise epitope is not known, but it has been mapped to the N-terminal portion of the protein.
