The digest solution and water elution were combined and dried to completeness and re-solubilized in 20 µl of MS-grade sample buffer (3% acetonitrile, 0.1% formic acid). The peptide concentration was determined using the Lunatic ultraviolet/visible polychromatic spectrophotometer. LC/MS/MS ...
To confirm complete biomass formation from methanol alone, we utilized13C metabolic tracer analysis and determined the13C labeled fraction of protein-bound amino acids by liquid chromatography coupled mass spectrometry (LC-MS) in MEcoli_ref_1 grown in medium containing no additional carbon sources (...
UV detection was conducted at 254 nm, and the HPLC and LC–MS/MS flow rates were 1.0 and 0.2 ml/min, respectively. Mobile phase A and B in HPLC-UV were water and acetonitrile (ACN), respectively, whereas mobile phase A and B in LC–MS/MS were 0.01 % acetic acid in water and ...
All reagents and solvents were of LC grade and purchased from Merck KGaA (Darmstadt, Germany). The purity of ethanol, IPA, methanol, 2-butanol, and acetonitrile were ≥ 99.90%, ≥ 99.90%, ≥ 99.97%, ≥ 99.00%, and ≥ 99.90%, respectively, as stated on the solvents’ specifi...
