Visualization of siRNA Knockdown


ViewRNA HC Screening Assay can be used for fast and easy quantitation and visualization of siRNA knockdown in cultured cells in a high throughput format. In this application, HPRT1 (target) and ACTB (control) are simultaneously detected in HeLa cells. The HPRT1 siRNA knockdown efficiency can be visualized and quantified. Read More ...


Compound Screening


ViewRNA HC Screening Assay was used for compound screening to simultaneously analyze the expression of three target mRNAs in HeLa cells. Read More ...


Time Course Studies


The assay can be very easily used for monitoring time course studies providing visual information as well as quantitative analysis. In addition one can analyze whole well data as well as understand expression heterogeneity within the cell population. In this application the expression of IL-6 (green) and IL-8 (red) in PMA induced HeLa cells was analyzed. Overall levels of IL-6 and IL-8 induction in HeLa cells at various time points after PMA treatment as determined by in situ analysis and QuantiGene 2.0 assay were in excellent agreement.
