... to the opsins found in the retina of the Japanese anchovy was determined by high performance liquid chromatography (HPLC). Furthermore, the opsin genes were cloned and sequenced, and the absorption spectra of different types of cones were determined by microspectrophotometry (MSP). These data were used...

.... HPLC reverse-phase C-18, used for measurement of ATP content, established a value of 1.62 μmol ATP g –1 dry mass in sponge medulla, as opposed to 0.04 μmol ATP g –1 dry mass in the cortex, thus indicating a specific and defined energy distribution. These results correlate with the mitochondria...
