Abstract
Recombinant proteins (RPs) are commonly expressed in bacteria followed by solubilization and chromatography. Purified RP yield can be diminished by losses at any step with very different changes in methods needed to try to improve yield. Time and labor can therefore be saved by first identifying the specific reason for low yield. The present study describes a new solid-state NMR approach to RP quantitation in whole cells or cell pellets without solubilization or purification. The approach is straightforward and inexpensive and only requires ~50 mL culture and a low-field spectrometer.

Abstract
Most proteins function in cells where protein concentrations can reach 400g/l. However, most quantitative studies of protein properties are performed in idealized, dilute conditions. Recently developed in-cell NMR techniques...

Most proteins function in cells where protein concentrations can reach 400g/l. However, most quantitative studies of protein properties are performed in idealized, dilute conditions. Recently developed in-cell NMR techniques can provide protein structure and other biophysical properties inside living cells at atomic resolution. Here we review how protein dynamics, including global and internal motions have been...
