Description

Cdp-Star CAS NO 160081-62-9 is a chemiluminescent substrate specifically designed for the highly sensitive detection of alkaline phosphatase (AP) in molecular biology applications. This compound is critical for achieving superior signal-to-noise ratios in blotting, hybridization, and immunoassay techniques. It is an essential reagent for researchers and diagnostic manufacturers in the life sciences, pharmaceutical development, and clinical diagnostics sectors who require reliable, high-performance detection systems.

Application

• Western Blotting: Primary chemiluminescent substrate for detecting alkaline phosphatase-conjugated antibodies.
• Nucleic Acid Hybridization: Used in Southern, Northern, and colony/plaque lift blots for detecting AP-labeled probes.
• Immunoassays: Key component in enzyme-linked immunosorbent assays (ELISA) and other solid-phase immunoassays.
• DNA Sequencing: Detection reagent for non-radioactive sequencing methods utilizing AP.
• Diagnostic Kit Manufacturing: Integral raw material for producing clinical diagnostic tests and kits.
• Microarray Analysis: Signal generation for high-throughput genomic and proteomic screening platforms.

Quality Control

Our Cdp-Star is manufactured under strict quality systems to ensure batch-to-batch consistency and performance. Each lot is subjected to rigorous analytical testing, including HPLC for purity and identity verification, to meet the exacting standards required for sensitive life science applications. A comprehensive Certificate of Analysis (COA) detailing purity, performance in standard assays, and absence of contaminating phosphatases is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. Due to its hygroscopic nature, allow the vial to equilibrate to room temperature before opening to prevent condensation and moisture uptake. For long-term stability, store desiccated.
