The facility is located in the Institute of Advanced Chemistry of Catalonia (IQAC-CSIC; Barcelona). It is equipped with a laboratory for the development and production of monoclonal antibodies. 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.

NANBIOSIS Scientific Women in the International Day of Women and Girls in Science

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[...]

New device could monitor treatments with anticoagulant to achive personalized therapies

Researchers from NANBIOSIS units 2 and 4 have designed a biosensor device based on gold nanostructures that precisely detects the presence of the anticoagulant drug from a small blood sample. Treatments with anticoagulants such as Sintrom® (acenocoumarol) face the difficulty of adjusting the drug doses. This device will allow patients to self-regulate the dose.   Researchers of NANBIOSIS unit 4  Biodeposition and Biodetection Unit of the Consejo Superior de Investigaciones Científicas (CSIC), the Catalan Institute of Nanoscience and Nanotechnology (ICN2) and CIBER Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN) have developed a biosensor device which allows the monitoring of anticoagulants such as Sintrom® (acenocoumarol) to[...]
