Despite intense interest and scrutiny focused on FOXP3 as a key protein & master transcription factor, isolating and enriching for viable FOXP3 positive cells remains a challenge. Although cell separation/staining via CD4+CD25+ selection is commonly used, this technique has limited applications. Thus, surface markers specific for FOXP3 positive cells would be invaluable research tools as they would:
• Facilitate isolation & purification of viable
Treg cells
• Distinguish naturally occurring
CD4+CD25+cells from both naive and
recently activated CD4+CD25-
nonregulatory T cells
• Allow therapeutic manipulation of
Treg cells
As the search for putative FOXP3+ markers continue, Neuropilin-1, GPR83, & FR4 have emerged as potential candidates. IMGENEX is excited to offer a panel of flow cytometric characterized antibodies against:
