| General description: | Adenine is a purine nucleobase that is a fundamental component of nucleic acids, including DNA and RNA. In the context of oligonucleotide synthesis, adenine is incorporated into synthetic DNA or RNA sequences. The USP Adenine standard ensures the purity and consistency of adenine used in the synthesis of oligonucleotides for research, therapeutic, and diagnostic purposes. The USP biologics oligonucleotides category includes a variety of synthetic nucleic acid sequences that are essential in research, diagnostics, and therapeutic applications. These oligonucleotides play crucial roles in molecular biology, including gene expression regulation, antisense therapy, and RNA interference. The USP provides comprehensive standards, reference materials, and analytical procedures to ensure the identity, quality, purity, and consistency of oligonucleotide products throughout their lifecycle. The United States Pharmacopeia (USP) provides quality standards for biologics to ensure their safety, efficacy, and quality throughout the manufacturing process. These standards assist manufacturers in adhering to regulatory requirements and help safeguard public health by reducing risks associated with biologics. |
