Automating Sample Preparation for MS Analysis of Recombinant Proteins
A research group from AlbaNova University Center, Royal Institute of Technology (Stockholm, Sweden) developed an automated method for purifying and desalting proteins before mass spectrometry analysis.
A research group from AlbaNova University Center, Royal Institute of Technology (Stockholm, Sweden) developed an automated method for purifying and desalting proteins before mass spectrometry analysis. The automated method was able to prepare as many as 48 samples in a 4.5-h period and used only small volumes of buffer. The method enabled the analysis of 19,000–35,000 Da recombinant proteins from crude and clarified cell lysates by electrospray ionization and matrix-assisted laser desorption–ionization mass spectrometry and gel electrophoresis.
RAFA 2024 Highlights: Contemporary Food Contamination Analysis Using Chromatography
November 18th 2024A series of lectures focusing on emerging analytical techniques used to analyse food contamination took place on Wednesday 6 November 2024 at RAFA 2024 in Prague, Czech Republic. The session included new approaches for analysing per- and polyfluoroalkyl substances (PFAS), polychlorinated alkanes (PCAS), Mineral Oil Hydrocarbons (MOH), and short- and medium-chain chlorinated paraffins (SCCPs and MCCPs).
