E. coli Cells Under Stress (IMAGE) Georgia Institute of Technology Caption This image shows E. coli cells under the stress of DHFR-targeting antibiotic trimethoprim in a 2015 study done prior to the research reported in this paper. The green color comes from GFP protein fused to DHFR and shows the uniform distribution of DHFR. The red color shows location of inclusion bodies of aggregated proteins in the cell.
