This unit is coordinated by the Nucleic Acids Chemistry Group at the Institute for Advanced Chemistry of Catalonia (IQAC), Spanish National Research Council (CSIC) and has the equipment needed for the production of oligonucleotides at low scale (mg to mg), purification, characterization and post-synthesis modification. The service counts with laboratories for synthesis and modification of oligonucleotides including DNA/RNA synthesizer, analytical and semi-preparative HPLC equipment for the purification and characterization of oligonucleotides. The service will focus in providing expert opinion to researchers as well as the production of tailored oligonucleotides. Routine synthesis of oligonucleotides used as primers will not be produced as there is a large number of commercial sources that provide a quick and low price service. The oligonucleotide synthesis platform will focus in providing modified oligonucleotides (ONs) that are difficult to obtain from commercial sources. These include microgram to milligram amounts of DNA and RNA derivatives carrying several modifications as well as oligonucleotide conjugates carrying lipids, membrane-receptors ligands, carbohydrates and peptides designed for therapeutic or diagnostic purposes. The facility benefits from the wide experience of Prof. Ramon Eritja that has more than 30 years expertise in the development of modified oligonucleotides.
FOR THOSE SERVICES IDENTIFIED AS OUTSTANDING, AT LEAST 20% OF THEIR CAPACITY IS OPEN UNDER COMPETITIVE ACCESS. SEE ANNEX 1 OF ACCESS PROTOCOL FOR DETAILS ON % OF OPENNESS FOR EACH SERVICE

Several CIBER-BBN groups at the University of Barcelona, the Institute for Advanced Chemistry of Catalonia (IQAC-CSIC), the Institute of Microelectronics of Barcelona (IMB-CNM-CSIC) and the Institute of Nanoscience and Materials of Aragon (INMA) —a joint institute of the CSIC and the University of Zaragoza (UNIZAR)— have developed a new method for detecting RNA viruses based on the technology of using probes that form triplex structures. This innovative methodology opens up new options to detect viruses such as SARS-CoV-2, the influenza A (H1N1) virus or the respiratory syncytial virus (RSV), a pathogen that affects newborns and requires differential diagnostic care. This[...]
Today, November 15 is a day of celebration for us, the Day of the Chemistry in Spain! Chemistry is the science that studies matter, how it is composed, its properties and how its structures are transformed and, as matter is everything, including living beings and ourselves, we can say that chemistry is omnipresent and transversal in all areas surrounding us. Chemistry is everywhere, we ourselves are chemistry and our health and our life is chemistry. “Everything around us is chemistry in the environment, foods, what we use and what we touch every day. Our own body is a sophisticated complex[...]

The discovery of the mRNA vaccines for the treatment of coronavirus, as well as new medicines for the treatment of genetic diseases, has been important in the quest of solutions for undrugable diseases in an unexpected short-time. Thus, the chemical modifications of nucleic acids with diagnostic and therapeutic purposes is now a reality, a revolution that promises to give hopes on unsolved medical problems or optimize previous approaches, largely due to the research push for the development of mRNA vaccines against SARS-CoV-2 infection. Now, the prestigious “The Chemical Record” journal has invited the Nucleic Acids Chemistry group, of IQAC-CSIC and[...]
At the end of the XXth century Nanotechnology appeared as one of the more powerful technologies for the future. At that time material sciences were able to produce nanomaterials with exquisite size control and atomic force, microscopy was able to visualize objects in the nanoscale and photolithography arrived to their physical limits in the preparation of computer chips threatening Moore’s law. This empirical law saying that as transistor components shrank, the number per chip doubled about every 18 months, was acting from 1971 (Intel’s first chip) to billions in the present times. At these times, one crucial development was t[...]
