Scientific BackgroundTranscriptional regulator which is crucial for the development and inhibitory function of regulatory T-cells (Treg). Plays an essential role in maintaining homeostasis of the immune system by allowing the acquisition of full suppressive function and stability of the Treg lineage, and by directly modulating the expansion and function of conventional T-cells.
A. Flow cytometryanalysis: paraformaldehyde fixed Jurkat cells (blue line), permeabilized with 0.5% Triton. Primary incubation 1hr (10 µg/mL) followed by Alexa Fluor 488 secondary antibody (4 µg/mL). IgG control: Unimmunized goat IgG (black line) followed by Alexa Fluor 488 secondary antibody. B. Western Blot: (1 µg/mL) staining of Human Muscle (A), (2 µg/mL) MOLT4 (B) and (1 µg/mL) negative control Pancreas (C) lysate (35 ug protein in RIPA buffer). Detected by chemiluminescence. C. Human Tonsil: (1 µg/mL) staining of paraffin embedded Human Tonsil. Microwaved antigen retrieval with Tris/EDTA buffer pH9, HRP-staining. A) Nuclear staining of scattered cells in the interfollicular area. B) High magnification of positive cells.
Human Blood Cells: staining of CD25-sorted (Treg) Human blood cells gathered by cytospin and detected by FITC (A) and in phase contrast (B).
Immunofluorescence analysis: paraformaldehyde fixed U2OS cells, permeabilized with 0.15% Triton. Primary incubation 1hr (10 µg/mL) followed by Alexa Fluor 488 secondary antibody (4 µg/mL), showing strong localization to nucleoplasm. The nuclear stain is DAPI (blue). Negative control: Unimmunized goat IgG (10 µg/mL) followed by Alexa Fluor 488 secondary antibody (4 µg/mL).
