New versus Old Phospho-STAT3 Assay Kit
Data show the superior performance of the new Phospho-STAT3 (Y705) Assay compared to the previous version of the assay
Stimulation of Phospho-STAT3 (Y705) in HeLa cells
Data show that treatment of HeLa cells with IFNα stimulates phosphorylation of STAT3 at Y705
Inhibition of Phospho-STAT3 (Y705) in HeLa cells
Data show that treatment of HeLa cells with JAK Innibitor 1 inhibits phosphorylation of STAT3 at Y705 by IFNα
Z'-factor determination in HeLa cells
The Z’-factor value of 0.73 indicates that the assay is robust and suitable for HTS
HeLa control lysate titration (QC Test)
Data show a linear relationship between lysate dilutions and TR-FRET ratio values
Phospho-STAT3 benchmarking-THUNDER
The THUNDER assay shows the highest S/B ratios between 1 and 4 hours of incubation
Phospho-STAT3 benchmarking-Company A
Company A assay shows a comparable S/B ratio to the THUNDER assay only after overnight incubation
Phospho-STAT3 benchmarking-Company B
Company B assay shows the lowest S/B ratios at all incubation times
Phospho-STAT3 stimulation in NIH/3T3 cells
Data show that treatment of NIH/3T3 cells with reference cytokines stimulates phosphorylation of STAT3 at Y705.
