Microscopic cytochemistry as matrix chemistry.

P van Duijn, M van der Ploeg

    Ciba Foundation Symposium
    |January 1, 1979
    PubMed
    Summary

    Artificial matrices aid in understanding microscopic cytochemical reactions. These models improve the specificity and quantitation of staining techniques by controlling variables within cellular structures.
