Zebrafish brain. ELF 97 Endogenous Phosphatase Detection Kit.
Endogenous phosphatase activity in the zebrafish brain, localized with the ELF 97 Endogenous Phosphatase Detection Kit (E6601). Enzymatic cleavage of the ELF 97 phosphatase substrate yields a bright yellow-green–fluorescent precipitate at the site of enzyme activity. The image was acquired with a bandpass filter set appropriate for the ELF alcohol precipitate.
