反相HPLC and adsorbent resins for the purification of oligonucleotide therapeutics and diagnostics.
The oligonucleotide market is growing rapidly due to the ability of oligonucleotides to alter (inhibit or augment) gene expression at the mRNA or DNA level. The largest class of therapies, AntiSense Oligonucleotides (ASO) therapies, works by silencing the production of mutated proteins that cause disease. The use of oligonucleotides is increasing in genetic research due to advances in CRISPR technology for DNA knockout studies. Growth in PCR-based diagnostics and microarray systems is increasing the demand for oligonucleotides as primers.
These oligonucleotide applications require precise targeting mechanisms for proper therapeutic or diagnostic function. Oligonucleotide synthesis is a complex process prone to errors in the base pair nucleic acid sequence. Oligonucleotide researchers and manufacturers need robust and selective purification strategies that are sensitive to minor differences in chemical and physical structure. We offer a range of chromatography resins to help companies optimize efficiency, resolution, and yield in oligonucleotide production, from benchtop to clinical trial to commercial scale.
寡核苷酸合成可以创建许多impurities that resemble the target sequence. Reverse Phase High Pressure Liquid Chromatography (RP HPLC) is a good way to get rid of impurities like failure sequences and base pair errors. It is an integral part of a downstream process that needs high recovery and high purity. Polymer RP HPLC resins are more durable than C18 silica resins and can withstand more extreme pH levels and aggressive cleaning protocols. DuPont™ AmberChrom™ chromatography resins can address these difficult oligonucleotide purification challenges:
