Abstract
Artificial cells containing invitro transcription and translation (IVTT) systems inside liposomes are important for the reconstruction and analysis of various biological systems. To improve the accessibility of artificial cell research, it is important that artificial cells can be constructed using only commercially available components. Here, we optimized the construction of artificial cells containing PUREfrex2.0, a commercially available IVTT with high transcriptional and translational activity. Specifically, the composition of the inner and outer s olutions of the liposomes and the concentrations of lipids, glucose/sucrose, potassium glutamate, and magnesium acetate were systematically optimized, and finally we found a protocol for the stable construction of artificial cells containing PUREfre×2.0. These findings are expected to be important in expanding the artificial cell research community.
