This video describes the technique of creating a zebrafish cardiomyopathy model with minimal variations among experimental groups and in the sample, we create zebrafish cardiomyopathy model using the drug doxorubicin.
Protocol
1. DOX Injection in Adult Fish Place a clean 100 mm Petri dish with a sponge inside it, under a dissection microscope, then adjust the focus. Cut the sponge to make a cavity of about 4 cm in length to hold a fish. Make a longer cavity for a larger fish. Prepare a 34 G needle with a 10 µL micro-syringe. Rinse the needle with 1x HBSS buffer to remove any bubbles and blocks from the syringe and tubing. Anesthetize the adult fish in embryo water containing 0.16 mg/mL tricaine for 2 min.<b…
