U937 cells were unstimulated (orange histogram) or stimulated for 15 minutes with Human IL-4 Recombinant Protein (Product # 200-04-50UG) (purple histogram). Cells were then stained intracellularly, using the Intracellular Fixation/Methanol protocol, with 0.25 ug Anti-Human/Mouse phospho-STAT6 (Y641) PE-Cyanine7. Viable cells were used for analysis, as determined by Fixable Viability Dye eFluor 780 (Product ... View More

Product Specific Information
Description
This CHI2S4N monoclonal antibody recognizes human and mouse signal transducer and activator of transcription 6 (STAT6) when phosphorylated on tyrosine 641. Following their phosphorylation by JAKs, STAT proteins translocate to the nucleus where they bind to DNA and regulate transcription of specific genes in a cell type- and cytokine-specific manner. In response to IL-4, STAT6 is phosphorylated on tyrosine 641 by JAK1 and JAK3. STAT6 signaling downstream of the IL-4 receptor promotes T cell growth and B cell production of IgE. Specificity of this CHI2S4N clone was determined by ELISA and flow cytometry.
Applications Tested: This CHI2S4N antibody has been pre-titrated and tested by intracellular staining followed by flow cytometric analysis of stimulated normal human peripheral blood cells. This can be used at 0.25 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.
Light sensitivity:
This tandem dye is sensitive photo-induced oxidation. Please protect this vial and stained samples from light.
Fixation:
Samples can be stored in IC Fixation Buffer (Product # 00-8222) (100 µL cell sample + 100 µL IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.
Excitation: 488-561 nm; Emission: 775 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser.
Target Information
STAT6 protein is a transcription factor activated by cytokines, particularly interleukin-4 and IL13. (Stat6-/-) were found to be deficient in IL-4-mediated functions including Th2 helper T-cell differentiation, expression of cell surface markers, T-cell proliferation, immunoglobulin class switching to IgE, and partial loss of IL-4 mediated proliferation. STAT6 mRNA has been detected in peripheral blood lymphocytes, colon, intestine, ovary, prostate, thymus, spleen, kidney, liver, lung and placenta. STAT6 is critically involved in Th2 immune response. STAT6 is crucial for IL-4-mediated biological responses, and naturally in two isoforms: STAT6a and STAT6c.
