Isotype

Mouse IgG1 kappa

Specificity

The mouse monoclonal antibody 3G3 recognizes N-terminal region of FoxP3, a 47-55 kDa transcription factor (intracellular antigen), which is the master regulator in the development and function of regulatory T cells.

Application

FC (QC tested)

Application details

Flow cytometry: Recommended dilution: 1-5 μg/ml. Intracellular staining.

Reactivity

Human, Mouse

Immunogen

Full-length His-tagged recombinant murine FoxP3

Antigen description

FoxP3 (forkhead box protein 3), a highly conserved forkhead/winged-helix transcription factor, plays a crucial role in maintaining immune homeostasis by governing the development and function of regulatory T cells. It is constitutively expressed at high level in CD25+ CD4+ Treg cells and at low level in a CD25- CD4+ Treg cell subset. Defects in gene encoding FoxP3 protein cause the scurfy phenotype in mice, and in human the IPEX syndrome (immune dysfunction, polyendocrinopathy, enteropathy, X-linked syndrome), also known as X-linked autoimmunity-allergic dysregulation (XLAAD) syndrome.
