In our latest paper, we address one of the most important concerns of the ISEV ISEV Communications Team: the quality of extracellular vesicle (EV) preparations. Obtaining pure EV preps from blood plasma is a very difficult task due to contaminants. (1/n)

Extracellular vesicles are present in samples in trace amounts, usually requiring large sample volumes. In this pre-print, we described a proteomics platform that requires only 50 uL of human plasma! Omics PNNL Science at PNNL Kristin Burnum-Johnson Samantha Powell biorxiv.org/content/10.110…

I am so excited to share our 🎉Nature Chemical Biology 🎉paper on my Department of Energy Early Career Award Research - Mapping 🔬microhabitats across a microbial community with Metabolome Informed Proteome Imaging (MIPI)! Environmental Molecular Sciences Laboratory (EMSL) Pacific Northwest National Laboratory DOE Office of Science nature.com/articles/s4158…

Excited to share our paper with Agilent Technologies on the implementation of nano-DESI imaging on a triple quad. Sensitive, specific, quantitative, and cost-effective platform - what can be better! Congrats to Miranda Weigand and co-authors! Purdue Chemistry pubs.acs.org/doi/full/10.10…

Brilliant application for studying symbiotic interactions by Marija Velickovic et. al. 😍 "microscale imaging across 12-µm-thick adjacent sections of Atta cephalotes fungal gardens and applied a metabolome-informed proteome imaging approach to map lignin degradation"

“We now have an understanding of how these natural systems degrade plant material. By looking at complex environmental systems at this level, we can understand how they are performing that activity and capitalize on it to make biofuels.” - Kristin Burnum-Johnson bit.ly/3uwbgfN

In our new paper, we used different insulitis models and mass spec techniques to study the roles of lipids during type 1 diabetes development. We ended up discovering how omega-3 fatty acids protect beta cells. link.springer.com/article/10.118…

👏 "Fun guy" Scott Baker is now a fungi fellow! Fungal biologist Scott Baker was elected as an @AIMBE Fellow. He leads Environmental Molecular Sciences Laboratory (EMSL)'s biological science area and is a Joint BioEnergy Institute (JBEI) joint appointee.

Congratulations to my husband, Grant E. Johnson, for being elected as an AAAS Fellow 🎉🎉

Join us at our ASMS Networking Session Celebrating Women Mass Spectrometrists, Monday June 3, 1 pm! Am Soc for Mass Spec

In this paper, we developed a method to purify extracellular vesicles from only 50 uL of plasma, and it takes only 15 min. We hope this method will enable large-scale extracellular vesicle proteomics analysis for biomarker studies. …iencejournals.onlinelibrary.wiley.com/doi/10.1002/pm…
