Phospho-STAT6 (Tyr641), PE, clone: CHI2S4N, eBioscience™
Mouse Monoclonal Antibody
Manufacturer: Life Technologies LS12901341
The protein encoded by this gene is a member of the STAT family of transcription factors. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. This protein plays a central role in exerting IL4 mediated biological responses. It is found to induce the expression of BCL2L1/BCL-Xcells, expression of cell surface markers, and class switch of immunoglobulins. Alternative splicing results in multiple transcript variants.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 Reported: This CHI2S4N antibody has been reported for use in intracellular staining followed by flow cytometric analysis.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 5 μL (0.125 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. Staining Protocol: We recommend using Protocol C: Two-step protocol: Fixation/Methanol. Protocol A: Two-step protocol: intracellular (cytoplasmic) proteins and Protocol B: One-step protocol: intracellular (nuclear) proteins cannot be used. All Protocols can be found in the Flow Cytometry Protocols: Staining Intracellular Antigens for Flow Cytometry Protocol located in the Best Protocols Section under the Resources tab online.Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser.Filtration: 0.2μm post-manufacturing filtered.
