Description

Poly(D(A,C,G,T)) CAS NO 31276-62-7 is a synthetic, defined-sequence oligonucleotide polymer composed of deoxyadenosine (dA), deoxycytidine (dC), deoxyguanosine (dG), and deoxythymidine (dT) nucleotides. This product serves as a critical research-grade standard and raw material for advanced molecular biology and diagnostic applications. It is essential for scientists and manufacturers in the biotechnology, pharmaceutical, and molecular diagnostics sectors who require high-purity, well-characterized nucleic acid polymers for their work.

Application

• Molecular Biology Research Standard: Used as a reference material for calibrating instruments and validating assays in PCR, sequencing, and hybridization studies.
• Diagnostic Kit Development: Serves as a key component in the formulation of positive controls and calibration standards for infectious disease and genetic testing kits.
• Biopharmaceutical R&D: Employed in the research and development of oligonucleotide-based therapeutics, including antisense drugs and aptamers.
• Next-Generation Sequencing (NGS): Utilized as a control library or spike-in to monitor sequencing run performance and data quality.
• Quality Control in Synthesis: Acts as a process control to verify the fidelity and efficiency of solid-phase oligonucleotide synthesis.
• Academic & Institutional Research: Provides a reliable substrate for fundamental studies on DNA structure, stability, and protein-nucleic acid interactions.

Quality Control

Our Poly(D(A,C,G,T)) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity assessment and mass spectrometry for sequence confirmation, to ensure it meets stringent research-grade specifications. Certificates of Analysis (COA) detailing identity, purity, and other critical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a non-frost-free freezer. This material is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature before opening to prevent condensation and moisture uptake. For long-term storage, consider desiccant.
