Development Stage
Research-Grade Signal Pathway Assay Development
Description
The SigPath™ ERK Phosphorylation Assay Kit offers a streamlined, cell-based ELISA for quantifying ERK1/2 phosphorylation without the need for cell lysate preparation. This high-throughput system normalizes phosphorylation levels to total cellular protein, ensuring exceptional accuracy for screening kinase inhibitors and studying MAPK signaling. By reducing assay time to just 6.5 hours, it provides a rapid and robust tool for drug discovery and signal transduction research in pre-clinical studies.
Features
Dual-Signal Precision: Measures phosphorylated ERK and total protein concurrently in the same well to ensure robust, normalized data accuracy.
Streamlined Workflow: Eliminates time-consuming cell lysis and protein transfer steps, reducing total assay time to approximately 6.5 hours.
High-Throughput Compatibility: Optimized for 96-well formats, facilitating rapid screening of thousands of compounds with automated liquid handling systems.
