In cells of the Malpighian tubes of Triatoma infestans Klug, the histone content reactive to the alkaline fast green method does not remarkably differ when nuclei with various heterochromatic patterns (T1 and T8) are compared to each other. The fast green-histone values for the euchromatins (and heterochromatins) of both nucleus types also appear not differing. However, the possibility that these histones are differently linked to DNA in euchromatin or heterochromatin variants is not to be ruled out. Cytochemical evidence is suggestive of a lysine-richness in the histones of the mentioned hetero- and euchromatins.
在克氏锥蝽的马尔皮基氏管细胞中，当比较具有不同异染色质模式（T1和T8）的细胞核时，对碱性固绿方法有反应的组蛋白含量没有显著差异。两种细胞核类型的常染色质（和异染色质）的固绿-组蛋白值似乎也没有差异。然而，不能排除这些组蛋白在常染色质或异染色质变体中与DNA的连接方式不同的可能性。细胞化学证据表明上述异染色质和常染色质的组蛋白富含赖氨酸。
