Live Cell Imaging: Studying NF-kB Signaling Dynamics Using the Operetta System
5 Nov 2012High content imaging provides a rapid and flexible tool to quantitatively study the intracellular localization of fluorescent markers on a single cell basis. In this application note from PerkinElmer a live cell imaging approach is presented for studying the nuclear translocation of NF-κB using the Operetta® High Content Imaging System. In contrast to fixed endpoint assays, this allows the negative feedback of NF-κB signaling, which results from NF-κB induced expression of IκB, to be analyzed. The use of Halo-tagged proteins on the Operetta system allows sensitive and flexible live cell assays to be performed for diverse high content screening applications.

High-Throughput ScreeningHigh-throughput screening (HTS) is an automated drug discovery technique for identification of active compounds against a compound library. Use HTS readers and integrated assay preparation / analysis workstations to screen your compounds. Identify active compounds against various HTS libraries, including membranes, proteins and peptides and HTS cell lines.

Microplate readers are generally distinguished by their mode of detection. Types include absorbance, luminescence, fluorescence intensity, fluorescence polarization, TRF / FRET and multimode microplate readers. Microplate readers deliver a high throughput of samples by reading multiple wells simultaneously, with the 96-well format the most commonly used. As a result, microplate readers are often used in the drug discovery, bioassays, research and pharmaceutical industries for screening applications. Microplate loading can also be automated, with robotic microplate stackers to increase throughput.

This technique provides in-depth insight into fast and complex biological processes, by allowing dynamic imaging of living cells instead of acquiring an individual image at a single point in time.High Content ImagingHigh content imaging is a method combining two or more fluorescent microscopy experiments to identify substances that alter a cell’s phenotype in a desired manner. The process is adapted to multi-well plates and both the image acquisition and analysis are automated.TranscriptomicsNF-κBCell Signaling
