Thereby, novel immunotherapeutic compounds can be developed for both human and veterinary patients. This study describes the radiolabeling of a canine anti-EGFR IgG antibody (can225IgG) with potential diagnostic and therapeutic value in comparative clinical settings. Can225IgG was functionalized with DTPA for subsequent chelation with the radionuclide 99mTc. Successful coupling of 10 DTPA molecules per antibody on average was proven by significant mass increase in MALDI-TOF spectroscopy, gel electrophoresis and immunoblots. Following functionalization and radiolabeling, 99mTc-DTPA-can225IgG fully retained its binding capacity towards human and canine EGFR in flow cytometry, immuno- and radioblots, and autoradiography. The affinity of radiolabeled can225IgG was determined to KD 0.8 ±0.0031 nM in a real-time kinetics assay on canine carcinoma cells by a competition binding technique. Stability tests of the radiolabeled compound identified TRIS buffered saline as the ideal formulation for short-term storage with 87.11 ±6.04% intact compound being still detected 60 minutes post radiolabeling. High stability, specificity and EGFR binding affinity pinpoint towards 99mTc-radiolabeled can225IgG antibody as an ideal lead compound for the first proof-of-concept diagnostic and therapeutic applications in canine cancer patients.","lang":"eng"}],"oa_version":"Published Version","main_file_link":[{"open_access":"1","url":"https://doi.org/10.18632/oncotarget.20914"}],"_id":"8235","doi":"10.18632/oncotarget.20914","author":[{"orcid":"0000-0002-8777-3502","first_name":"Judit","full_name":"Fazekas-Singer, Judit","id":"36432834-F248-11E8-B48F-1D18A9856A87","last_name":"Fazekas-Singer"},{"last_name":"Berroterán-Infante","full_name":"Berroterán-Infante, Neydher","first_name":"Neydher"},{"last_name":"Rami-Mark","full_name":"Rami-Mark, Christina","first_name":"Christina"},{"first_name":"Monika","full_name":"Dumanic, Monika","last_name":"Dumanic"},{"full_name":"Matz, Miroslawa","first_name":"Miroslawa","last_name":"Matz"},{"full_name":"Willmann, Michael","first_name":"Michael","last_name":"Willmann"},{"full_name":"Andreae, Fritz","first_name":"Fritz","last_name":"Andreae"},{"last_name":"Singer","full_name":"Singer, Josef","first_name":"Josef"},{"first_name":"Wolfgang","full_name":"Wadsak, Wolfgang","last_name":"Wadsak"},{"full_name":"Mitterhauser, Markus","first_name":"Markus","last_name":"Mitterhauser"},{"first_name":"Erika","full_name":"Jensen-Jarolim, Erika","last_name":"Jensen-Jarolim"}],"quality_controlled":"1","title":"Development of a radiolabeled caninized anti-EGFR antibody for comparative oncology trials","publication_identifier":{"issn":["1949-2553"]},"intvolume":"         8","language":[{"iso":"eng"}],"date_updated":"2021-01-12T08:17:39Z","volume":8,"extern":"1","type":"journal_article"}
