Deskripsi
Several proteins are expressed at too low abundance in the Escherichia coli (E. coli) proteome to be detected by standard methods. Here, the authors create a microfluidics-based platform enabling single-molecule counting of low-abundance proteins by mechanically slowing-down their diffusion in live E. coli.
