【摘要】 用分子筛凝胶层析法从L783白血病小鼠的脾脏、胸腺和淋巴结中分离出病毒颗粒并予以逆转录酶活性的测定。逆转录反应受核糖核酸酶（RNase）抑制;放线菌素D在低浓度时无抑制,而在较高浓度时有轻度抑制;二价金属离子,尤以Mn²⁺比Mg²⁺对活性更有促进作用;无机磷酸盐对反应也有抑制作用。实验结果表明,小鼠L783白血病病毒属逆转录病毒。更多还原

【Abstract】 The viruses of L783 transplantable lymphooytio mouse leukemia were isolated by the gel ohromatography and the activity of their reverse transoriptase was detected. The experimental results suggest that the viruses isolated belong to retrovirus.更多还原
