Protein quantification using mass spectrometry

The FZB is the lung research center of the Leibniz Association and is therefore committed to the motto “theoria cum praxi”.

The FZB sees its scientific and socio-political task in basic, disease- and patient-oriented lung research and training in this field. The field of research includes chronic inflammatory diseases of the lung of infectious and non-infectious environmental and behavioral origin. Research focuses on tuberculosis, infections with non-tuberculous mycobacteria and other bacterial ...

Human aortic smooth muscel cells (Thermo Fisher Scientific, C-007-5C, LOT: 2164581) were treated with TGB1 or PDGF/L1B to induce the contractile or synthetic SMC phenotype. As part of a multi-omics analysis, we conducted mass spectrometry to quantify protein levels of cell lysates using a HPLC-ESI-MS/MS system (HPLC=high pressure liquid chromatography, Ultimate 3000 UPLC system; ESI=electrospray ionization) and an Orbitrap Exploris™ 480 mass spectrometer. MS data were analyzed and normalized with ...
