Quantitative Nucleic Acid Histochemistry of the Yolk Sac Syncytium of Oviparous Teleosts: Implications for Hypotheses of Yolk Utilization

  • W. E. Bachop

In the yolk-sac syncytium of the muskellunge embryo, Esox masquinongy ohioensis Kirtland, there are nuclei whose size and staining properties with basic dyes suggest that their chromatin content is greater than that of other embryonic nuclei (Bachop, 1965). This study is intended to test that supposition, using a histochemical test specific for one of the constituents of chromatin and using a microspectrophotometer to quantify the histochemical reaction in different nuclei relative to each other. The rationale of microphotometry is that insertion of the microscope in the optical train, and substitution of a dyed tissue on a slide for a dye solution in a cuvette, does not militate against using Beer’s law to deduce relative concentration of dye molecules from relative absorption of light (Pollister and Ornstein, 1959).
