Project description:Sponge samples were analyzed on the QExactive in positive ESI mode without and with metal infusions (ca, vanadium, mg) and (fe, cu, zn).
Project description:Select species were grown in Brain-Heart-Infusion supplemented with 1 mM cholic acid and 0.1 mM taurine for 16 hours. Data are in positive ion mode.
Project description:Molecular networking has become a key method to visualize and annotate the chemical space in non-targeted mass spectrometry data. We present feature-based molecular networking (FBMN) as an analysis method in the Global Natural Products Social Molecular Networking (GNPS) infrastructure that builds on chromatographic feature detection and alignment tools. FBMN enables quantitative analysis and resolution of isomers, including from ion mobility spectrometry.
