cytophotometry

Thân thiện

A scientist uses cytophotometry to analyze stained cells on a slide.

Definition

1. Noun:
   • The measurement of the concentration or amount of chemical compounds within a cell using a cytophotometer: Cytophotometry is a scientific technique that involves analyzing cells by measuring the light they absorb or emit after being stained with specific dyes. This allows for the quantitative study of cellular components like DNA, RNA, or proteins.

Usage Examples

• Noun:
  • Cytophotometry was used to determine the DNA content of the tumor cells.
  • The research relies on precise cytophotometry to analyze protein expression levels in individual neurons.

Advanced Usage

• "Flow cytophotometry": A more advanced, automated form of the technique where cells in a fluid stream pass through a laser beam for rapid analysis.
  • Flow cytophotometry allows for the high-speed sorting and analysis of thousands of cells per second.

Variants and Related Words

• Cytophotometer (n): The specialized instrument used to perform cytophotometry.
  • The laboratory recently acquired a new digital cytophotometer.
• Cytophotometric (adj): Relating to or obtained by cytophotometry.
  • The cytophotometric data confirmed our hypothesis.

Synonyms

• Microspectrophotometry: A closely related technique for measuring light absorption of microscopic specimens.
• Cell photometry: A more general, less technical term for the measurement of light properties in cells.

Related Phrases

• "To perform cytophotometry": To carry out the cytophotometric analysis.
  • The technician was trained to perform cytophotometry on tissue samples.
• "Cytophotometry analysis/results": The data or findings obtained from the technique.
  • The cytophotometry results indicated abnormal cell growth.
