FYI for GNPS2 users, we are doing server room maintenance over the weekend with power going down in 1 hour.

Published in @J_ASMS, just in time for #ASMS24! A quick bottom line - ModiFinder helps you to quickly solve structures by localizing modifications in Molecular Networking and Analog Library Search pubs.acs.org/doi/full/10.10…

If sampling the International Space Station sounds interesting to you, join me Monday morning at #ASMS2024 to hear our story!

🎉I am excited to share my latest first-author publication in @an_chem! We introduce MobiLipid, a tool for #lipidomics using #IonMobility-#MassSpectrometry, which facilitates CCS quality control & correction through internal standardization. doi.org/10.1021/acs.an…

Here we show that prior to 2022, the metabolite Lac-Phe was mis-annotated in @Metabolon datasets as “1-carboxyethylphenylalanine.” We use this information to identify physiologic urine Lac-Phe transporters. Incredible detective work by @veronical1411 biorxiv.org/content/10.110…

I am happy to share that a part of my PhD work is now available as a preprint: "MobiLipid: A Tool for Enhancing CCS Quality Control of Ion Mobility-Mass Spectrometry Lipidomics by Internal Standardization." doi.org/10.26434/chemr… #Lipidomics #IonMobility #CSS #MassSpectrometry

If you enjoy bile acids, then this will be a fun read and a resource for you. It shows that we can begin using untargeted metabolomics big data mining using a mass spec query language to discover new molecules in animals and humans. cell.com/cell/fulltext/…

Our lab is excited to share a preprint on localizing the site of structural modifications for small molecules using ModiFinder. For those using Molecular Networking, we hope this will speed up the process of structural elucidation when propagating from known compounds.

Call to the microbiome community. We are building a collaborative microbial metabolite center (CMMC) knowledgbase resource to allow direct connection of microbiome derived molecules, their producers and activities. If you have published papers and want to add your 1/

What happens when you can't assign a complete structure in MS or NMR? Aside from a lower confidence level & maybe a Markush, you can't get an InChI - or can you? We tried to explore this in our "InChI Isotopologue and Isotopomer Specifications" preprint: researchsquare.com/article/rs-372…

Good news: Our newest research just went online! We improve plasmid production by shifting the metabolism of cells via sulfate in the growth medium. Read the details here: doi.org/10.1186/s12934…

From a reunion during #SETAC #NonTarget2022, a really fun collaboration bloomed! Maternal exposure to 6PPD and 6PPDQ transfers to the brain of unborn mice fetus. Plus, 6PPDQ acts as a strong agonist towards RARα and RXRα pathways! pubs.acs.org/doi/10.1021/ac…
