1894 Amer. Naturalist 28 975 Œdematin corresponds, in part at least, to Heidenhain's oxychromatin, Pfitzner's parachromatin, and Schwarz' paralinin.
1895 Jrnl. Royal Microsc. Soc. 159 ‘Oxychromatin’ and ‘cyanophilous granulation’ are independent structural parts of the chromatin framework.
1924 E. G. Conklin in E. V. Cowdry Gen. Cytol. ix. 550 The oxychromatin which escapes into the cell body at mitoses is often more abundant than that which goes to form the chromosomes.
1948 W. Andrew tr. E. D. P. de Robertis Gen. Cytol. vii. 140 With ultracentrifugation the nucleus is deformed and the nuclear structures are stratified in the following layers..: (1) nucleolus, (2) basichromatin, (3) oxychromatin, (4) karyolymph.
1949 Amer. Naturalist 83 101 The form of the chromosome is due primarily to the protein thread (definitely non-histone and identified with oxychromatin) of the ‘residual chromosome’.
