Overview
Although the synthesis process of oligonucleotides is very efficient, impurities or invalid sequences are still introduced during the synthesis process. Therefore, the analysis of the synthetic product and the determination of its purity are very important.
Our company is equipped with a quality control laboratory to provide comprehensive testing services for oligonucleotides. These services ensure that the delivered DNA or RNA oligonucleotides meet the quality requirements of various downstream applications in the experiment.
Our Services
Our services are mainly as follows:
Sequence Identification
Our company ensures the accuracy and integrity of the sequence by sequencing the sequence of oligonucleotide products or impurities. This is critical for a variety of research and therapeutic applications.
Purity Detection
In order to ensure the efficacy, accuracy, safety and biological activity in the production and research of oligonucleotides, the detection of oligonucleotide purity is particularly important. Our company uses advanced analytical methods to identify the purity of oligonucleotides.
Stability Study
Through forced degradation studies, accelerated and long-term stability studies, our company assesses the stability of oligonucleotide products under different environmental conditions. This helps to identify degradation pathways to recommend optimal storage conditions.
Solvent Residue Analysis and Test
The presence of residual solvents will not only affect the quality of products, but also lead to drug safety problems. Our company provides solvent residue analysis services for the detection and quantification of residual solvents in oligonucleotide samples.
Element Impurity Analysis
Our company uses inductively coupled plasma mass spectrometry (ICP-MS) technology to detect and quantify trace element impurity levels. This helps to ensure the purity and safety of oligonucleotide products.
Water Detection
Water content is not a fixed property of oligonucleotides, but a reflection of their current environment. However, the determination of moisture is still very valuable. For example, moisture content may be an indicator of the success of a drying operation or the integrity of a container closure system. Our company provides water detection services for oligonucleotide products.
Analysis and Detection of Microorganisms and Endotoxins
Using validated microbiological methods and endotoxin detection assays, our company ensures the safety and sterility of oligonucleotide products. This helps meet regulatory requirements for pharmaceutical and biomedical applications.
