An electrophoretic analysis has been carried out on the total protein of lampbrush chromosomes, nucleoli and nuclear sap, obtained from newt oocyte nuclei. In each case, distinctive and heterogeneous banding patterns are observed. The absence of detectable quantities of histones in occyte chromatin is noted. In the case of the lampbrush chromosome preparation, it is concluded that all protein species are derived from the ribonucleoprotein matrix of the lateral loops.
对从蝾螈卵母细胞核中获得的灯刷染色体、核仁及核液的总蛋白进行了电泳分析。在每种情况下，均观察到独特且不均一的条带模式。注意到卵母细胞染色质中未检测到组蛋白。就灯刷染色体标本而言，得出的结论是所有蛋白质种类均源自侧环的核糖核蛋白基质。
