DNA/RNA Drug pH Testing Characterization Service is an analytical service designed for evaluating the physicochemical properties of oligonucleotide drugs, aiming to comprehensively assess their acid-base characteristics and the impact on stability, solubility, and functional activity through precise pH testing. The pH value is one of the core parameters in nucleic acid drug quality control, as it not only determines the conformation and binding capacity of the drug in both in vivo and in vitro environments but also directly influences storage conditions, formulation design, and the safety and efficacy of clinical applications.
During the research and production of nucleic acid drugs, different pH conditions may cause degradation of the nucleotide backbone, instability of chemical modification groups, or significant changes in solubility, which in turn affect the pharmacokinetic properties and therapeutic outcomes of the drug. Therefore, systematic pH testing not only helps researchers determine the optimal storage range and formulation conditions of the drug but also enables early identification of potential degradation pathways and stability risks, providing critical data support for preclinical development, process optimization, and quality control.
