Abstract:

Single-cell translation assay for highly parallel readout of reporter protein expression kinetics after mRNA transfection. a Micropatterned protein arrays are used for highly parallel readout of single-cell kinetics on standardized protein adhesion spots, which enables the observation of thousands of cells over a long time period. The microscopy image shows the micropatterned area of one channel with cells expressing eGFP. b Schematics of the six-channel sample holder and the scanning time-lapse acquisition mode. Stacks of images from individual panels are depicted on the right. c Schematic illustration of the transfection process using mRNA containing lipoplexes. The mRNA, which is released into the cytosol, is translated into a fluorescent reporter protein. The translation dynamics are modeled by biochemical rate equations. d Single-cell eGFP expression is measured by integration over the fluorescence intensity. The zoom-in shows one eGFP-expressing cell confined on a fibronectin square (dashed square). The recording of protein expression begins by adding the mRNA lipoplexes, which are incubated for 1?h. e A subset of the single-cell trajectories of eGFP expressing cells shows the heterogeneity within the population. The thick black trajectory corresponds to the mean protein expression dynami
