Quantifying Cellular Capacity to Identify Gene Expression Designs With Reduced Burden

BioRxiv : the Preprint Server for Biology
Francesca CeroniTom Ellis


Heterologous gene expression can be a significant burden to cells, consuming resources and causing decreased growth and stability. We describe here an in vivo monitor that tracks E. coli capacity changes in real-time and can be used to assay the burden synthetic constructs and their parts impose. By measuring capacity, construct designs with reduced burden can be identifiedand shown to predictably outperform less efficient designs, despite having equivalent expression outputs.

BioRxiv & MedRxiv Preprints

BioRxiv and MedRxiv are the preprint servers for biology and health sciences respectively, operated by Cold Spring Harbor Laboratory. Here are the latest preprint articles (which are not peer-reviewed) from BioRxiv and MedRxiv.
