Short Description
Quantifies LKB1 (Ser431) phosphorylation levels using a sandwich ELISA method.
Development Stage
Research-Grade Signal Pathway Assay Development
Description
The SigPath™ Human/Mouse LKB1(S431) Phosphorylation ELISA Kit provides a rapid and sensitive solution for measuring pLKB1(S431) levels directly in cultured cells. By normalizing phosphorylation to total protein content within the same well, this high-throughput system eliminates cell lysis steps, ensuring precise data for screening inhibitors and studying tumor suppressor signaling pathways in drug discovery.
Features
Superior Sensitivity: Employs high-affinity antibody pairs for precise detection of endogenous phospho-LKB1 levels in diverse cell lysates and tissue samples.
Dual-Species Reactivity: Offers validated performance across both human and mouse models, ensuring seamless cross-species experimental consistency and reliable data translation.
Optimized Assay Format: Streamlined sandwich ELISA protocol minimizes hands-on time while delivering robust, reproducible results through standardized, pre-coated microplate components.
Phospho-Specific Accuracy: Specifically targets the Serine 431 residue, eliminating cross-reactivity with non-phosphorylated isoforms for high-fidelity signaling pathway analysis.
Process Relevance
Quantifying LKB1 phosphorylation status to evaluate AMPK-related metabolic regulation and ensure consistency in therapeutic signaling modulation assays.
Application Stage
