PATHscan - Target-Specific Signaling Pathway Panel

LeadHunter® Discovery Services provides you access to a comprehensive collection of cell-based pathway indicator assays designed to detect activation or inhibition of complex signal transduction pathways in response to compound treatment. Based on the proven PathHunter® technology, these stable cell lines allow you to measure distinct events within a variety of pathways involved in compound toxicity, cholesterol metabolism, antioxidant pathways, DNA damage, ER stress and many others to drive your lead discovery and optimization without relying on reporter gene assays or complex phenotypic screens. 

Comprehensive Menu

PathHunter® Pathway Assays are novel, non-imaging functional whole cell assays for measuring multiple cellular signaling events such as protein translocation, secretion, degradation and expression using highly sensitive and quantitative chemiluminescent detection. This approach can be applied to any cell signaling cascade in which a target protein either degrades, translocates or is secreted. These assays serve as pathway indicators.
