Test Overview
Flow Cytometry
Mutations of the FoxP3 gene have been described in patients with immune dysregulation, polyendocrinopathy, enteropathy, X-linked syndrome (IPEX). This assay uses flow cytometry to determine the proportion and intensity of intracellular FoxP3 protein expression in the subset of CD4+ T cells that are CD25 bright and CD127 negative. The PCH101 antibody reacts with the amino terminus of human foxp3 protein.
