Abstract
Nucleases are found in different fractions of nerve cells in the rat brain. The nuclease denaturating preferably the one-chain DNA at pH 8.0 is located chiefly in the neuron nuclei. Fractions of cell nuclei containg mainly neuron nuclei or glial nuclei were obtained by the method of ultracentrifugation within the sucrose gradient.
摘要
核酸酶存在于大鼠大脑神经细胞的不同组分中。在pH 8.0时优先使单链DNA变性的核酸酶主要位于神经元细胞核中。通过蔗糖梯度超速离心法获得了主要包含神经元细胞核或神经胶质细胞核的细胞核组分。
