1. A technique for measuring the light absorption or fluorescence of individual cells or cellular components using a microscope and photometric instruments.
Usage: technical; biology; used in cell biology and medical research

Examples

• Cytophotometry allows researchers to quantify DNA content in cell nuclei.
• The laboratory uses cytophotometry to measure protein concentrations within living cells.
• Cytophotometry has become an essential tool in cancer diagnosis and classification.
• Using cytophotometry, scientists can detect changes in cellular composition during disease progression.
• The microscope was equipped with cytophotometry capabilities to analyze fluorescent markers in the tissue sample.
