Laser Refractometer as a Transfer Standard of the Pascal

July 9, 2016
Author(s)
Patrick Egan, Jack A. Stone Jr., Jacob Edmond Ricker, Jay H. Hendricks
We have developed a new low pressure sensor which is based on the measurement of (nitrogen) gas refractivity inside a Fabry-Perot (FP) cavity. We compare pressure determinations via this laser refractometer to that of well-established ultrasonic manometers

Interconversion of Peptide Mass Spectral Libraries Derivatized with iTRAQ or TMT Labels

July 7, 2016
Author(s)
Zheng Zhang, Xiaoyu Yang, Yuri A. Mirokhin, Dmitrii V. Tchekhovskoi, Weihua Ji, Sanford P. Markey, Pedatsur Neta, Bowen A. Michael, Stephen E. Stein
Derivatizing peptides with isobaric tags such as iTRAQ and TMT is widely employed in proteomics due to their ability to multiplex quantitative measurements. We recently made publicly available a large peptide library derived from iTRAQ 4-plex labeled

Perfluorinated Alkyl Acids in the Plasma of South African Crocodiles (Crocodylus niloticus)

July 1, 2016
Author(s)
Jessica L. Reiner, John Bowden, Ian Christie, Matthew P. Guillette, Theresa M. Cantu, Russell H. Lowers, Hannes Botha, Wilmien Luus-Powell, Willem J. Smit, Danny Govender, Danie Pienaar, Louis J. Guillette Jr.
Perfluorinated alkyl acids (PFAAs) are environmental contaminants that have been used in many products for over 50 years. Interest and concern has grown since 2000 on the widespread presence of PFAAs, when it was discovered that PFAAs were present in

Identification of novel N-glycosylation sites at non-canonical protein consensus motifs

June 14, 2016
Author(s)
Mark S. Lowenthal, Kiersta S. Davis, Lisa E. Kilpatrick, Catherine A. Mouchahoir, Karen W. Phinney
N-glycosylation is well known to occur at asparagine residues in the canonical consensus sequence N-X-S/T, but has also been identified at a small number of N-X-C motifs including the Asn491 residue of human serotransferrin. Here we report additional novel

XAFS Data Interchange: A single spectrum XAFS data file format

June 9, 2016
Author(s)
Bruce D. Ravel, M. Newville
We propose a standard data format for the interchange of XAFS data. The XAFS Data Interchange (XDI) standard is meant to encapsulate a single spectrum of XAFS along with relevant metadata. XDI is a text-based format with a simple syntax which clearly
