We use DNA synthesizer to synthesise oligonucleotides by adopting the solid-phase phosphoramidite method. This is currently the mature and mainstream oligonucleotide synthesis method. We are capable of synthesising oligonucleotides using not only the basic building blocks, such as deoxynucleosides and ribonucleosides, but also chemically modified nucleosides, such as florescence labelled deoxynucleosides.
A purification process is required to obtain high-purity end-product. Purification is the key to the quality of oligonucleotide synthesis. Techniques we currently use for oligonucleotides purification include desalting purification, PAGE purification, affinity purification, and HPLC purification. Oligonucleotides are widely used in most life sciences laboratories and it is well-suited for various applications in molecular biology and medical research. For example, oligonucleotides are used as primers in both DNA sequencing and DNA amplification. Oligonucleotides also serve as probes in various DNA and RNA detection and analysis. Oligonucleotide synthesis products are needed essentially by almost every laboratory in life sciences research.
As a well-recognised provider of customised oligonucleotides in China, we have 22 years of experience in perfecting the production of oligonucleotides. We have a capacity of producing over 10,000 oligonucleotides (about 200,000 bases) per day, adopting different types of purification methods. We are also able to successfully synthesise complex and rare oligonucleotides. A stringent quality assurance system is implemented to ensure the process is carried out in a quality-controlled environment. Please see the section headed “Business — Quality Assurance” for details of our quality control policies and procedures.

Custom gene synthesis technology is extremely versatile and applicable to many different research areas, such as genetics, the regulation of gene expression, and the functional research of gene and drug discovery. We use the oligonucleotides made in oligonucleotides synthesis as starting materials for gene synthesis. Gene synthesis involves such techniques as amplification, cloning, nucleic acid purification and error correction, etc
We are one of well-recognised gene synthesis suppliers in the PRC. We have developed our gene synthesis technology platform and established comprehensive service processes. Through years of research and development, we have obtained such patents as “Synthesis method of gene containing repetitive sequences” and “Fluorescent clone screening vector and preparation and application thereof,” and have obtained unique experience and expertise in gene optimisation and complex gene synthesis. With over 10 years of experience combined with our unique technology, we are able to offer reliable gene synthesis product at attractive and affordable prices.
