Oligonucleotide Purity Analysis Services
Oligonucleotide purity analysis is a critical step for precisely determining the purity of synthesized nucleic acids such as DNA, RNA, and siRNA. Impurities can markedly compromise the quality, stability, biological activity, and experimental reproducibility of oligonucleotides. Accurate purity assessment identifies synthetic by-products, degradation fragments, and other contaminants, thus ensuring reliable downstream experiments. Given the widespread applications of oligonucleotides in gene synthesis, PCR amplification, RNA interference, gene editing, and drug development, purity assurance is essential.
MtoZ Biolabs provides precise and reliable Oligonucleotide Purity Analysis Services utilizing cutting-edge analytical platforms and an expert scientific team, empowering your research and development with rigorous quality control.

Case Study
Case 1
This research demonstrated that two-dimensional liquid chromatography (2D-LC) coupled with mass spectrometry (MS) significantly enhances the analytical precision for antisense oligonucleotides. Researchers successfully developed a high-resolution 2D-LC/MS strategy combining ion-pair reversed-phase chromatography (IPRP), anion-exchange chromatography (AEX), and hydrophilic interaction chromatography (HILIC), enabling detection of impurities at levels as low as 0.3%. Compared to conventional IPRP-MS methods, this novel approach avoided issues associated with TEA and HFIP, improving mass spectrometry sensitivity, instrument longevity, and separation efficiency via online desalting through HILIC.

FAQ
Q1: How do we select an appropriate oligonucleotide purity analysis method?
MtoZ Biolabs recommends selecting methods based on your specific research objectives, intended applications, and regulatory requirements. For high-sensitivity and high-resolution analyses such as drug development or quality control, chromatographic techniques like UPLC or IEC effectively distinguish target sequences from impurities. If detailed structural characterization and precise molecular weight determination are required, incorporating high-resolution mass spectrometry (e.g., ESI-MS) is strongly advised.
Q2: Can your Oligonucleotide Purity Analysis Services analyze modified oligonucleotides?
Yes. Our Oligonucleotide Purity Analysis Services fully support analysis of modified oligonucleotides, including fluorescently labeled, phosphorothioate-modified, sugar-modified, and other chemically altered nucleic acids. By combining high-performance chromatography with high-resolution mass spectrometry, we accurately distinguish modified oligonucleotide targets from impurities, ensuring rigorous quality control aligned with stringent research and regulatory standards.
Q3: What should we consider when submitting oligonucleotide samples for analysis?
Samples submitted should ideally have initial purity levels of 80% or higher, provided as dried powder or nuclease-free aqueous solutions to prevent contamination or degradation. To optimize analytical outcomes, clients should supply detailed sequence information, modification types, and potential impurity profiles. MtoZ Biolabs’s technical specialists assist with preliminary consultations and sample preparation guidance, ensuring streamlined workflows and reliable analytical results.
