摘要
EMS诱变的细胞经过Brdu递增浓度的定向筛选,建立了可以抗300mg/L浓度Brdu的斜纹夜蛾胸苷激酶缺陷型细胞株.经[3H]胸苷磷酸化反应测定胸苷激酶(TK)活力表明。
A Spodoptera litura cell line deficient in thymidine kinase activity (Sl TK -) was isolated by mutagenesis with Ethylmethanesulfonate (EMS) and serial passages in the presence of 5’ bromodeoxyuridine(Brdu) at stepwise increasing concentrations. The resulted Sl TK cell line was confirmed to be lacking in TK activity by unable to catalyze the phosphorylization of thymidine.
