Interferon Response (STAT1) Pathway Products
Introduction
SwitchGear Genomics offers a panel of 88 transfection-ready reporter constructs to allow you to measure STAT1 pathway activation. The SwitchGear STAT1 promoter targets were picked from our genome-wide promoter collection based on sequence motif analysis, expression studies, and transcription factor binding data. We conducted experiments to generate a profile across the set of constructs with and without STAT1 activation. These data are summarized in the heatmap below. SwitchGear offers the complete pathway profiling panel of constructs in a plate format that allows you to characterize the effects of many conditions across the entire STAT1 pathway. We also offer a smaller subset of key responder constructs that show a strong induction response and can be used as biomarkers in screening applications.
STAT1 Biomarker Set - 8 promoters, 2 controls
The selected constructs shown in the graph are the 8 of the highest responding promoters under our chosen test conditions*. The chart summarizes the induction ratios for each construct in Hela human cervical carcinoma cells that were transfected with promoter-reporter constructs and treated with 500u/mL interferon alpha or vehicle only for 8 hours. The Y-axis shows the treated/untreated signal ratio on a log scale and error bars represent one standard deviation. Please see the heatmap below for relative promoter activities in an untreated setting.

The selected constructs (as shown in the heatmap) represent the SwitchGear STAT1 Profiling Plate. The heatmap summarizes the untreated activity and induction response for each construct in the pathway profiling plate using one common induction strategy (see above)*. On the right side of the figure, the colors represent log2 transformed ratios of treated/untreated activity according to the color scale shown at the base of the heatmap. Black indicates no change, and intensity of red or blue indicates levels of induction or repression, respectively. On the left side, the intensity of yellow parallels the activity of the promoter in the unstimulated or untreated condition. All untreated signals are relative to the highest and lowest values within the individual experiment.(“IFNa”= Hela cells treated with 500 U/ml interferon alpha for 8 hours; “IFNg”= Hela cells treated with 100 ng/ml interferon gamma for 8 hours).
*Experimental results and absolute values of luciferase units may vary depending on cell line, treatment, and protocols. The data should be used as a guide for selecting candidate promoters and panels for your particular experimental design.
