The Innovative Regional Growth Core BioOK is a confederation of five companies, one Steinbeis Transfer Center, the Federal Centre for Breeding Research on Cultivated Plants and the University of Rostock with the objective to develop a complete portfolio effective and adapted analytical procedures for transgene specific risk assessment procedures of genetically modified plants.  The network includes molecular characterisation, compound analysis, feeding studies, toxicology and allergenicity tests, greenhouse and field trials, analysis of effects on target and non target organisms, soil and micro organisms as well as post-marked monitoring.As model substances we are analysing five different recombinant plant-derived proteins (two marker proteins and three proteins with technical and pharmaceutical value) to support practicability and comparison to previously applied methods. The commonly used and well analysed marker NPTII serves as a control to for the comparison to previously used methods to validate the new procedures, GFP (green flourescent protein) is used as visible marker protein to standardise new in vitro test systems, Cyanophycin (poly l-aspartate chain with l-arginine residues) is a protein of technical value, VP60 (structural protein of RHDV (rabbit haemorragic disease virus)) is a member of subunit vaccines and finally the well known and characterised adjuvant CTB (non-toxic Subunit B of the Choleratoxin).The potato plant has been selected as the model plant because of the high biosafety standard and the storage organ (tuber) with a high industrial value and the possibility to do feeding analysis.
