Phospho-STAT1 (Tyr701) cellular kit
All-in-one kit for robust detection of Phospho-STAT1 (Tyr701)
This HTRF kit enables the cell-based quantitative detection of STAT3 phosphorylated on Tyr705, as a readout of the JAK/STAT signaling pathway.
This HTRF cell-based assay enables rapid, quantitative detection of STAT3 phosphorylated on Tyr705 as a readout of JAK/STAT signaling activity. STAT3 is upregulatd in many cancers, making it a powerful tool in anti-cancer research.
HeLa cells were grown for 2 days in a T175 flask 37°C, 5%Co2. Stimulation was done with 5nM of IFNa for 15min. Cell culture medium was eliminated and cells supplemented with 3ml of lysis buffer before incubating for 45min. Soluble supernatants were collected after 10min centrifuging. Equal amounts of lysates were used for a side by side comparison of WB and HTRF. The two methods show a comparable sensitivity level: 750 cells. HTRF offers superior convenience over western blot.
HeLa cells (100,000 cells/well) were incubated for 1 hour at 37°C with various concentrations of antagonist. Agonist (IFNα) was then added and incubated for 30 minutes. After a 30-minute lysis incubation time, phosphorylated STAT3 was measured using the two-plate assay protocol of the HTRF phopsho-STAT3(Tyr705) cellular assay kit.
Hela cells (100,000 cells/well) were activated with IFNa for 15 min, using the two-plate assay protocol of the Phospho-STAT3 (Tyr705) and Total-STAT3 assays. Results obtained show a dose-response increase of STAT3 phosphorylation upon IFNα stimulation, while STAT3 expression level remains constant.
In response to cytokines and growth factors, STAT3 is phosphorylated by receptor-associated kinases and then forms dimers that translocate to the cell nucleus, where they act as transcription activators. STAT3 mediates the expression of a variety of genes in response to cell stimuli, and thus plays a key role in many cellular processes such as cell growth and apoptosis. The binding of Interleukin 6 - family cytokines to the gp130 receptor triggers STAT3 phosphorylation by JAK2. STAT3 is also a target of other receptors such as RTKs (EGFR, cmet.) and c-src.
