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

Cancer is one of the world’s leading causes of death, with over 18.1 million cases and 9.6 million deaths in 2018. One of the most successful drugs used in chemotherapy for the treatment of diverse severe cancers is 5-Fluorouracil (5-FU), however, one of the major problems described in clinical practice is 5-FU cell resistance. Resarchers of the Nucleic Acids group and the Colloidal and interfacial Chemistry Group of CIBER-BBN at IQAC-CSIC have collaborated in a research to inspect and test the ability of parallel G-quadruplexes to deliver floxuridine oligonucleotides into different types of cancer cells; finally, the internalization ability and[...]
Today February 11 is the International Day of Women and Girls in Science, a day to raise awareness of the gender gap in science and technology. According to the United Nations, while yet women and girls continue to be excluded from participating fully in science, science and gender equality are vital to achieve the internationally agreed development goals, including the 2030 Agenda for Sustainable Development. Thus, in recent years, the international community has made a great effort to inspire and promote the participation of women and girls in science. NANBIOSIS wants to acknowledge the efforts made by scientific women who struggle every day to contribut[...]
In the frame of the collaboration of three units of NANBIOSIS, researchers of CIBER-BBN Groups proposed a strategy to simultaneously deliver anticancer drug pairs, composed by a tumor-targeted protein nanoparticle and an antiproliferative drug, with specific activ-ity for the same type of cancer. These three units are: NANBIOSIS U1 Protein Production Platform (PPP), at IBB-UAB, led by Toni Villaverde y Neus Ferrer NANBIOSIS U18 of Nanotoxicology Unit, at Institut de Recerca. Hospital de la Santa Creu i Sant Pau, led by Ramón Manques and Isolda Casanova, and NANBIOSIS U29 Oligonucleotide Synthesis Platform (OSP) at IQAC_CSIC, led by Ramón Eritja and[...]

The book “Nucleic Acids Chemistry” takes the most important aspects of the methodology of oligonucleotides synthesis, that is currently expanding by the endorsement of a dozen of new medicines, such as the first medicine based on interfering RNA for the control of LDL and cholesterol in blood that will facilitate the decrease of cardiovascular illnesses. The writing[...]
Researchers of CIBER-BBN Units of NANBIOSIS: U29 Oligonucleotide Synthesis Platform (OSP) at IQAC_CSIC, led by Prof. Ramón Eritja and U10 Drug Formulation, at UPV-EHU, led by Prof José Luis Pedraz, are coauthors of an article published by International Journal of Pharmaceutics. Gene therapy strategies based on non-viral vectors are currently considered as a promising therapeutic option for the treatment of cystic fibrosis (CF), being liposomes the most commonly used gene carriers. Niosomes offer a powerful alternative to liposomes due to their higher stability and lower cytotoxicity, provided by their non-ionic surfactant and helper components. In this work, a three-formulation screening is[...]
