Short summary
A novel cell-free protein synthesis system called eCells produces amino acids based on specific isotopes using low-cost precursors. The system selectively labels methyl groups, i.e valine and leucine, with high efficiency. eCells achieve high levels of 13C incorporation and deuteration in protein preparations, making them suitable for NMR experiments of large protein complexes. They are easy to prepare, can be scaled up in volume and are a promising tool for protein production and NMR studies.
