Macrophotometric, histological and histochemical, and microphotometric
methods were used in the study.
Postnatal development and sublobular distribution of cytochrome P-450 in rat liver: a microphotometric
techniques were used to measure the light absorption characteristics of phytoplankton at the single-cell level.
They had subjected the original plate to a microphotometric
analysis, a standard procedure used to determine precise wavelengths and intensities.
