In Search of Putative FOXP3+ Cell Surface Markers

November 18th, 2008

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:

• Neuropilin-1 (clone 211H6.01)

• GPR83 (polyclonal)

• Folate Receptor 4 (clones 12A5 & TH6)

Flow cytometric analysis of intracellular FOXP3 (IMG-5802D) and cell surface FR4 with clone 12A5 (IMG-6217C) (left) and clone TH6 (IMG-6218C) (right) at 0.06 ug/10^6 mouse splenocytes.

Flow cytometric analysis of Neuropilin-1 in CD4+CD25+ human PBMCs using A) an isotype control & B) DDX0440 at 0.5 ug/10^6 cells. These antibodies are available in multiple sizes and conjugates.

IMGENEX India Pvt Ltd. the only biotech company in Orissa and one of its kinds in Eastern India. IMGENEX India started in Oct as an outsourcing branch of IMGENEX Corporation, San Diego, USA.
