Stat6 (Phospho-Tyr641) Antibody

The Stat6 (Phospho-Tyr641) Antibody from Assay Biotechnology is a polyclonal antibody that specifically recognizes the phosphorylated form of Stat6 at Tyr641. Stat6 is a member of the STAT family of transcription factors and plays a vital role in mediating cellular responses to cytokines and growth factors. Upon activation by interleukin-4 (IL-4) and other signaling molecules, Stat6 undergoes phosphorylation by receptor-associated kinases and forms homo- or heterodimers. These dimers then translocate to the nucleus, where they act as transcription activators, influencing the expression of genes involved in IL-4-mediated biological responses.

Importance and Function of Stat6

Stat6 is known to induce the expression of BCL2L1/BCL-X(L), a key protein responsible for the anti-apoptotic activity of IL-4. Knockout studies in mice have demonstrated its involvement in T helper 2 (Th2) cell differentiation, cell surface marker expression, and class switch of immunoglobulins. Dysregulation of Stat6 signaling has been implicated in various diseases, highlighting the significance of understanding its phosphorylation status and activity.

Reactivity in Human, Mouse and Rat Samples

The Stat6 (Phospho-Tyr641) Antibody demonstrates broad reactivity, making it suitable for use in various species including human, mouse, and rat. This broad reactivity allows researchers to investigate Stat6 phosphorylation and activity across different model organisms, facilitating translational research and comparative studies. By utilizing this antibody, researchers can explore the similarities and differences in Stat6 signaling among different species, providing comprehensive insights into its function and regulation. The antibody’s reactivity in multiple species enhances its versatility and applicability in diverse research areas, including immunology, cancer biology, and developmental biology, among others.

High Specificity – Detects endogenous levels of Stat6 protein only when phosphorylated at Y641

The Stat6 (Phospho-Tyr641) Antibody exhibits exceptional specificity in detecting the phosphorylated form of Stat6 at Tyr641. It recognizes endogenous levels of Stat6 protein only when phosphorylated at this specific tyrosine residue. This high specificity ensures accurate and reliable detection of phosphorylated Stat6 and minimizes the potential for cross-reactivity with non-phosphorylated Stat6 or other proteins. By selectively targeting the phosphorylated form of Stat6, researchers can confidently assess its activation status and gain insights into the phosphorylation-dependent signaling events mediated by Stat6. This specificity is crucial for obtaining precise and meaningful data, enabling a better understanding of Stat6-mediated cellular responses and their role in various physiological and pathological processes.
