What is the respiratory burst?
The respiratory burst is a rapid release of reactive oxygen species by phagocytes to kill pathogens.
How is the respiratory burst measured?
It is measured using fluorescence after activating phagocytes with a chemical agent.
Why use zebrafish embryos for this assay?
Zebrafish embryos are a useful model for studying innate immune responses due to their transparency and genetic tractability.
What are reactive oxygen species?
Reactive oxygen species are chemically reactive molecules containing oxygen that play a role in cell signaling and defense against pathogens.
Can this method be adapted for other organisms?
Yes, the assay can be modified for use in other model organisms to study immune responses.
