cytophotometry
/ˌsʌɪtə(ʊ)fə(ʊ)ˈtɒmɪtri
/noun [mass noun] Biology
The investigation of the contents of cells by measuring the light they allow through after staining.The micronuclei of wild-type pairs provided a reliable diploid standard to quantify the macronuclear DNA content of exconjugants by cytophotometry....
- The results of fluorescence cytophotometry showed that cells containing tetraploid nuclei gradually increased in number.
- The determination of tumor heterogeneity and tumor cell proliferation by means of DNA cytophotometry gives valuable clues regarding prognosis.

cytophotometer
- The existence and amount of genome size variation within species of higher plants have been topical since the early days of genome size research, when commercial cytophotometers became available.
- Measurements of stained nuclei occur in the cytophotometer, a device consisting of a microscope, a photometer, and an integrator.
- Joanna is also determining the effects of the radiation on DNA replication by using an absorption cytophotometer.
cytophotometric
- The cytophotometric analyses have been limited to a relatively small number of nuclei and simply showed the presence or absence of one or two genomic copies of DNA.
- Using histochemical and cytophotometric methods, enzymes responsible for the membrane transport in the developing sporocyst of Fasciola hepatica were studied.
