Intraperitoneale Injektion: Eine Methode zur Verabreichung einer Lösung in die Bauchhöhle eines erwachsenen Zebrafisches

Executive Industry Relevance

Intraperitoneal injection in adult zebrafish enables precise delivery of compounds into the abdominal cavity, supporting infection modeling and immune response studies. This technique provides a reproducible method for compound administration in zebrafish, aiding target validation and phenotypic screening in early discovery. It enhances predictive confidence by allowing controlled delivery of therapeutic candidates or pathogens in a disease-relevant system.
