The laboratory is fully equipped for obtaining, selecting and storing monoclonal antibody producing hybridomas. In addition, the facility has infrastructure for the production of polyclonal antibodies, as well as laboratories for the synthesis of bioconjugates, haptens, the purification of antibodies and the performance of immunoassays. In addition to the above mentioned equipment, the IQAC-CSIC provides animal husbandry facilities and a unit for the synthesis of organic molecules.

The equipment consists in an inverted phase contrast microscope with a camera, two Class II laminar flow biological safety cabinets, two CO2 incubators, a bioreactor for hybridoma culture, and tangential filtration unit for purification of the antibodies produced in the culture. Among the items of available equipment it should be highlighted a spotter for selection of high antibody producing cell lines and an automated ELISA microplate washer an ELISA reader, two AKTA Prime Liquid chromatography systems for antibody purification, plus standard equipment (centrifuges, fridges, liquid nitrogen containers, autoclave, baths, and vacuum equipment) and all the necessary routine laboratory apparatus.Cabs also has access to a fully equipped chemistry laboratory for the synthesis of haptens and immunoreagents.

Description

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.

Ethylcellulose nanoparticles as new “in vitro” tool for cell transfection

Researchers of NANBIOSIS U12 Nanostructured liquid characterization unit and U29 Oligonucleotide Synthesis Platform (OSP) of CIBER-BBN at IQAC-CSIC have obtained successfully ethylcellulose nanoparticles with positive zeta potential formed from nano-emulsion complexation with an antisense oligonucleotide which result very promising complexes for “in vitro” cell transfection. A new non-viral gene delivery vector has been developed, based on ethylcellulose, an easily available and low cost carbohydrate polymer, “generally recognized as safe” by the FDA. Although ethylcellulose is nonionic, positively charged nanoparticle dispersions have been obtained using nano-emulsion templates in cationic:non-ionic surfactant-based systems. The nanoparticles have been successfully complexed with negatively charged phosphorothioate antisens[...]

This work is focused on entrapping cationic nioplexes within supramolecular hydrogels based on N-protected phenylalanine. To modulate the supramolecular hydrogel diffusion properties, hydrogels were easily tuned with ĸ-carrageenan (≤ 1%). These materials were fully characterized using rheology. The niosomal liberation in solution through hydrogels was monitored by fluorescence and this release was[...]
