Comprehensive Analysis of Tryptic Peptides Arising from Disulfide Linkages in NISTmAb and Their Use for Developing a Mass Spectral Library

June 22, 2021
Author(s)
Qian Dong, Xinjian Yan, Yuxue Liang, Sanford Markey, Sergey L. Sheetlin, Concepcion Remoroza, William E. Wallace, Stephen Stein
This work presents methods for identifying and then creating a mass spectral library for disulfide-linked peptides originating from the NISTmAb. Analysis involved both partially- reduced and non-reduced proteins under neutral and weakly basic conditions

Creation and Release of an Updated NIST DART-MS Forensics Database

June 17, 2021
Author(s)
Edward Sisco, Arun Moorthy, Laura M. Watt
Facing increasing caseloads and an everchanging drug landscape, forensic laboratories have been implementing new analytical tools. Direct analysis in real time mass spectrometry (DART-MS) is often one of these tools because it provides a wealth of

Copper-binding anticancer peptides from the piscidin family: an expanded mechanism that encompasses physical and chemical bilayer disruption

June 16, 2021
Author(s)
Fatih Comert, Frank N. Heinrich, Ananda Chowdhury, Mason Schoeneck, Caitlin Darling, Kyle Anderson, M. Daben J. Libardo, Alfredo Angeles-Boza, Vitalii I. Silin, Myriam Cotten, Mihaela Mihailescu
In the search for novel broad‑spectrum therapeutics to fight chronic infections, inflammation, and cancer, host defense peptides (HDPs) have garnered increasing interest. Characterizing their biologically‑active conformations and minimum motifs for

Trace element proxies and stable isotopes used to identify water quality threats to elkhorn coral (Acropora palmata) at two national parks in St. Croix, USVI

June 11, 2021
Author(s)
Amanda L. Bayless, Steven J. Christopher, Jennifer Ness, Colleen E. Bryan Sallee, Russell D. Day, Cheryl M. Woodley, C. Anna Toline
Chronic biological impairments of reef organisms have been documented at two national parks in St. Croix, USVI. Although several water quality parameters have been out of compliance with USVI water quality criteria, whether these parameters or other

Witnessing the survival of time-energy entanglement through biological tissue and media

June 9, 2021
Author(s)
Daniel J. Lum, Michael Mazurek, Alexander Mikhaylov, Kristen M. Parzuchowski, Ryan M. Wilson, Marcus Cicerone, Ralph Jimenez, Thomas Gerrits, Martin Stevens, Charles Camp
In this work, we demonstrate the preservation of time-energy entanglement of near-IR photons through thick biological media ( 1.55 mm) and tissue ( 235 um) at room temperature. Using a Franson-type interferometer, we demonstrate interferometric contrast of
