Questions and Answers

What is the primary goal of applying the method to several specimens of presumed GloFish® from traders in the Netherlands and Germany?

To detect the presence of transgenic fish.

What is the significance of measuring the fluorescence of water-soluble protein in zebrafish?

It allows for a rapid screening of genetically modified zebrafish.

What is the 'skinbow' zebrafish, and how was it created?

The 'skinbow' zebrafish is a genetically engineered fish that exhibits a wide range of colors, created by injecting a gene that codes for red, blue, and green fluorescent proteins into single-cell fish embryos.
