The PathScan® Phospho-Stat6 (Tyr641) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of Stat6 protein phosphorylated at Tyr641. A Stat6 Mouse mAb has been coated onto the microwells. After incubation with cell lysates, Stat6 (phospho or nonphospho) protein is captured by the coated antibody. Following extensive washing, Phospho-Stat6 (Tyr641) Rabbit Detection Antibody is added to detect the captured phospho-Stat6 protein. Anti-rabbit IgG, HRP-linked Antibody is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of the absorbance for this developed color is proportional to the quantity of Stat6 phosphorylated at Tyr641.Antibodies in kit are custom formulations specific to kit.
REACTIVITY
Human

Background: Upon activation by Janus kinases, Stat6 translocates to the nucleus where it regulates cytokine-induced gene expression. Stat6 is activated via phosphorylation at Tyr641 and is required for responsiveness to IL-4 and IL-13 (1-4). In addition, Stat6 is activated by IFN-α in B cells, where it forms transcriptionally active complexes with Stat2 and p48 (5,6). Protein phosphatase 2A is also involved in regulation of IL-4-mediated Stat6 signaling (7).

The FastScan™ Phospho-Stat6 (Tyr641) ELISA Kit is a sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of Stat6 when phosphorylated at Tyr641. To perform the assay, sample is incubated with a capture antibody conjugated with a proprietary tag and a second detection antibody linked to HRP, forming a sandwich with phospho-Stat6 (Tyr641) in solution. This entire complex is immobilized to the plate via an anti-tag antibody. The wells are then washed to remove unbound material. TMB is then added. The magnitude of observed signal is proportional to the quantity of phospho-Stat6 (Tyr641). Antibodies in kit are custom formulations specific to kit.
