GenScript offers up to 218 nt DNA oligo synthesis and comprehensive 200+ modifications & labeling to meet research needs in biology, diagnostics (qPCR & NGS), and drug discovery. GenScript provide high purity oligo with optimized PAGE+/HPLC+ etc., processes under ISO 13485 for MDx kit.
DNA oligos produced by GenScript's state-of-the-art oligo-synthesizer have substantial purity with low truncated sequences. Each oligo is meticulously monitored during synthesis and controlled according to GenScript's stringent quality assurance and quality control standards. The final product is identified by mass spectrum and its purity is analyzed by high throughput capillary gel electrophoresis or HPLC based on the purification option.
We specialize in oligonucleotides labeled by fluorescent or non-fluorescent dyes, quencher pairs or electrochemicals for qualitative and quantitative detection.

# GenScript recommends PAGE/PAGE+ purification for primers of 151-200 nt. For PAGE-purified primers shorter than 150 nt, if you prioritize cost-effectiveness and faster turnaround times, you can choose ePAGE; if you prioritize higher purity, you can choose HPLC or HPLC+.
Please pay attention to base code when place order.
Please refer to the purification method selection guide.
