Publication number: 20150104596Abstract: Prior art for processing human cell or tissue biopsy specimens implies the individualization of the specimens by marking the specimen containers (e.g. for transportation) and the specimen holders (e.g. plastic cassettes, glass slides) but not the specimen itself. The specimen processing steps include several manual transfers of the specimens between different containers and specimen holders. This manual transfer may result in specimen mix-ups. These specimen mix-ups can be prevented by attaching solvent resistant uni- or multicolored barcoded cuttable strips of cellulose acetate directly to the specimens thereby marking and individualizing the specimen itself. The strips adhere to the specimens at all steps of tissue processing and evaluation.Type: ApplicationFiled: November 3, 2011Publication date: April 16, 2015Inventor: Ulrich Felix Vogel
