LightSwitch Pathway Reporter Stable Cell Lines simplify the task of measuring the response of specific pathways to treatment with various compounds or growth conditions. Each cell line contains a stably integrated regulatory element that has been cloned upstream of our optimized RenSP luciferase reporter gene. Each had been validated for use in measuring the activity of a specific biological pathway in that particular cell line. As they can be used in a variety of different plate-based formats, the Pathway Reporter Stable Cell Lines are ideal for both primary and secondary high-throughput screening.
