Between 2023 and 2025, a dedicated infrastructure for in vitro and in vivo experiments was established on site. The operation of zebrafish husbandry was initiated in 2024 and is being reported.Methods A modular biolab in container design was installed on campus to accommodate biological research. In August 2024, the first phase of the FLASHlab@PITZ animal laboratory began operation with zebrafish (Danio rerio). The Max Delbrück Center for Molecular Medicine had prepared a genetically diverse starting wild-type AB group for breeding. A fish care was established under standardized husbandry protocols, including stable temperature, and continuously monitored water chemistry to ensure a healthy environment and reliable breeding. Breeding was done at a 1:2 male-to-female ratio in spawning tanks. The embryo generation methodology was prepared to provide consistent access for future experiments.Results A healthy and genetically diverse zebrafish population is being maintained with reliable embryo yield required for high-throughput radiation testing. Husbandry and environmental parameters, as well the breeding performance met the experimental requirements.Conclusion With its newly established infrastructure, FLASHlab@PITZ is ready to perform standardized irradiation studies using zebrafish embryos (≤ 120 hours post-fertilization) as a high-throughput model of normal tissue sparing effect. Initial experiments with conventional X-rays will establish a standardized reference framework for comparison with subsequent electron beam exposure studies which should help to provide a selection of optimal irradiation parameters 000643496 536__ $$0G:(DE-HGF)POF4-621$$a621 - Accelerator Research and Development (POF4-621)$$cPOF4-621$$fPOF IV$$x0 000643496 693__ $$0EXP:(DE-H253)PITZ-20150101$$5EXP:(DE-H253)PITZ-20150101$$ePhoto Injector Test Facility$$x0 000643496 8564_ $$uhttps://bib-pubdb1.desy.de/record/643496/files/FRPT_Grebinyk_abstract.pdf$$yRestricted 000643496 8564_ $$uhttps://bib-pubdb1.desy.de/record/643496/files/FRPT_Grebinyk_abstract.pdf?subformat=pdfa$$xpdfa$$yRestricted 000643496 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1103334$$aDeutsches Elektronen-Synchrotron$$b0$$kDESY 000643496 9131_ $$0G:(DE-HGF)POF4-621$$1G:(DE-HGF)POF4-620$$2G:(DE-HGF)POF4-600$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lMaterie und Technologie$$vAccelerator Research and Development$$x0 000643496 9201_ $$0I:(DE-H253)Z_PITZ-20210408$$kZ_PITZ$$lTechnologie$$x0 000643496 980__ $$aabstract 000643496 980__ $$aEDITORS 000643496 980__ $$aVDBINPRINT 000643496 980__ $$aI:(DE-H253)Z_PITZ-20210408 000643496 980__ $$aUNRESTRICTED
