Methods and systems for increasing the stability of a nucleic acid template that encodes a protein of interest in a cell free translation system or a ribosomal display reaction system are described. In some embodiments, the nucleic acid template is an RNA or mRNA. The stability of the RNA template is increased by adding the bacteriophage lambda protein Gam to the cell free extract used in the translation system. The addition of Gam protein increases the longevity of the reaction system, thereby increasing the efficiency of the ribosomal display reaction system.
本文描述了在细胞自由翻译系统或核糖体显示反应系统中提高编码相关蛋白质的核酸模板稳定性的方法和系统。在某些实施方案中,核酸模板是 RNA 或 mRNA。在翻译系统中使用的无细胞提取物中加入噬菌体λ蛋白 Gam,可增加 RNA 模板的稳定性。Gam 蛋白的加入增加了反应系统的寿命,从而提高了核糖体显示反应系统的效率。
