ELPEN’s Experimental Research Center is set up under Greek law, in line with the pertinent EU legislation (Directive 63/2010 – Presidential Decree 56/2013), and according to suggestions and guidelines by major international organisations, such as the Association for Assessment and Accreditation of Laboratory Animal Care International (AAALAC Int.) and the Federation of European Laboratory Animal Science Associations (FELASA). In this respect, we have also taken into account any new forthcoming EU legislation. In addition, we adhere to principles of collegiality, democracy, individual accountability and unremitting internal control at all levels. Ongoing documentation and updates help further enhance and increase productivity and quality.
