There is provided inter alia a process for stabilizing a eukaryotic cell line which expresses PylRS and tRNAPyl and which is suitable for incorporation of a gene encoding a target protein containing one or more non-natural amino acids encoded by a nonsense codon which comprises culturing said cell line under conditions in which the adverse effect of tRNAPyl expression on cell viability and/or cell growth is reduced or eliminated.
除其他外,还提供了一种稳定真核细胞系的方法,该细胞系表达 PylRS 和 tRNAPyl,适于加入编码含有一个或多个由无意义密码子编码的非天然氨基酸的目标蛋白质的基因,该方法包括在减少或消除 tRNAPyl 表达对细胞活力和/或细胞生长的不利影响的条件下培养所述细胞系。
