Research in the Marty Lab is centered on characterization of membrane proteins by mass spectrometry. Our lab works at the interface of chemistry and biochemistry, combining cutting-edge analytical methodologies with biotechnology.
Prof. Marty on NPR
Prof. Marty sat down with Arizona Public Media to discuss their new work with antimicrobial peptides with Prof. Leslie Tolbert. Listen to the interview here: https://radio.azpm.org/p/radio-azscience/2019/8/23/157065-episode-196-molecules-and-the-battle-against-bacteria/.
National Science Foundation CAREER Award
Congratulations to Prof. Marty on receiving an NSF CAREER award! This will fund new work in the lab on using native MS to study interactions of membrane active compounds such as antimicrobial peptides with lipid nanodiscs. It also supports ongoing development of UniDec. New tutorials for UniDec will be coming soon. Finally, it also supports development of the ASEMS-V program to engage Veterans in STEM Research in collaboration with the University of Arizona ASEMS program and the VETS center. Stay tuned...
New Article in Analytical Chemistry
Congrats to Larry, Elaine, Julia, and Will on their new article in Analytical Chemistry on using native MS to study antimicrobial peptide complex formation and lipid interactions in nanodiscs. It launches a new direction in the Marty lab on studying antimicrobial peptides in intact nanodiscs by native MS.

New Article in the Journal of the American Society for Mass Spectrometry
Congrats to Marius, Alex, Deseree and Jibriel on their new article in JASMS. This work focuses on native MS analysis of nanodiscs with a wider range of lipids, including glycolipid GM1, cardiolipin, and sterols. It also include our first results with Saposin A nanoparticles. Great work!

New Article in the Journal of the American Chemical Society
Congrats to James, Dane, Guozhi, Ciara, and Deseree on the publication of their paper in JACS! This work demonstrated the first native MS measurement of membrane protein oligomeric state within a lipid bilayer environment. Deseree did an awesome job sketching the concept below. Thanks also to collaborators in the Pemberton and Prell labs. Well done team!
