Oligonucleotide Synthesis

Oligonucleotide manufacturing and development expertise

Since our inception in 1985, we have been developing fluorescence-based nucleic acid probe technologies that strongly rely on automated DNA synthesis. Our long-standing, in-house oligonucleotide synthesis expertise makes us industry leaders.

Over the years, we have introduced hundreds of innovative specialty phosphoramidites and solid supports including minor groove binders (MGB), unique modified nucleobases, fluorophores, and quenchers. We have developed and optimized the manufacturing and quality control of thousands of high complexity nucleic acid probes and PCR primers in the cGMP environment. We offer a vertically integrated system of production: all steps are performed in-house, starting from the development of specialty reagents to the synthesis of probes and primers and final diagnostic kit assembly.

We understand the oligonucleotide needs of end users because we are end users ourselves. Our proprietary reagents and techniques serve to provide labeled probes with the desired physicochemical properties and, additionally, to simplify the probes’ synthesis and purification. Our comprehensive catalog for nucleic acid labeling includes a wide range of fluorescent dyes, modified nucleobases, minor groove binders and quenchers in a variety of reagent forms. The modifications in our catalog can be considered building blocks for the researcher’s imagination.


Custom oligonucleotide synthesis

DNA synthesis services

DNA synthesis services are essential for various research applications, including gene editing, gene silencing, and synthetic biology. EGMDx provides custom DNA synthesis services that are tailored to meet the specific needs of researchers and biotech companies. We use technology, brainpower, and quality control measures to ensure the purity and accuracy of our synthesized DNA products. Our team also provides modifications, labeling, and purification options upon request.

Oligonucleotide modifications

Oligonucleotide modifications are essential for various research applications, including gene expression analysis, aptamer development, and siRNA delivery. EGMDx offers a range of modification options, including fluorescent dyes and other labels, to customize oligonucleotides for specific research needs. We set a high bar for ourselves in performance to ensure purity and accuracy of our modified oligonucleotides. We provide custom designed oligonucleotide sequences with modifications upon request.

Purification and quality control

Oligonucleotide purification and quality control are critical steps to ensure excellent output of synthesized oligonucleotides. EGMDx provides oligonucleotide purification services, including HPLC to remove impurities and ensure purity of product. Our facility for manufacturing oligonucleotides is cGMP compliant and ISO 13485 certified.
