Definition of cytochemistry in US English:



  • The chemistry of living cells, especially as studied microscopically.

    • ‘Fluorescence microscopy is less invasive than electron microscopy and can be applied to living cells through the use of green fluorescent protein-fusion proteins or fluorescence analog cytochemistry.’
    • ‘The laboratory's role in identifying leukemic blasts by morphology and cytochemistry remains important for initial diagnosis.’
    • ‘The relationship between the timing of these changes in the cytochemistry of the chalazal cells and the timing of the changes in grain water content and grain dry weight which occur during grain development has not been established.’
    • ‘With no tissue remaining, only destained sections can be used for cytochemistry or immunohistochemistry, which might impair the final evaluation.’
    • ‘Until recently, visualization of cytoskeletal filaments was mainly limited to immunofluorescent staining of fixed cells or fluorescent analog cytochemistry for living cells.’
    • ‘Instruction in cytology and cytochemistry would follow later in both the lab and the classroom.’
