Structural Fingerprinting of siRNA Therapeutics by Solution NMR Spectroscopy

August 4, 2022
Author(s)
Owen Becette, Anh Tran, Jace Jones, John Marino, Robert Brinson
Nucleic acids are an increasingly popular platform for the development of biotherapeutics to treat a wide variety of illnesses, including diseases where traditional drug development efforts have failed. To date, there are 14 short oligonucleotide

Effect of Tribologically-Induced Changes in Surface Termination of Silicon-Containing Diamond-Like Carbon Coatings on the Resistance to Biomolecule Adsorption

August 1, 2022
Author(s)
Cherno Jaye, Daniel A. Fischer, Zixuan Li, Jennings Z. Ye, Jieming Yan, Nicolas Molina, Hsu-Ming Lien, Robert Chrostowksi, Jianliang Lin, Mangolini Mangolini
Silicon-containing diamond-like carbon (DLC) is a class of thin-film materials with excellent mechanical properties, high thermal stability, and good tribological performance over a wide range of environmental conditions. While non-alloyed/non-doped DLCs

NMR and Metabolomics -A Roadmap for the Future

July 23, 2022
Author(s)
Tracey Schock, David Wishart, Leo Cheng, Valerie Copie, Arthur Edison, Hamid Eghbalnia, Jeffrey Hoch, Goncalo Gouveia, Wimal Pathmasiri, Robert Powers, Llyod Sumner, Mario Uchimiya
Metabolomics investigates global metabolic alterations associated with chemical, biological, physiological, or pathological processes. These metabolic changes are measured with various analytical platforms. While liquid chromatography-mass spectrometry (LC

Selective C-terminal Conjugation of Trypsin-Digested Peptides for Proteomic Measurements

July 20, 2022
Author(s)
Tian Xie, Alexandria Brady, Cecilia Velarde, David Vaccarello, Nicholas Callahan, John Marino, Sara Orski
Bottom-up proteomic experiments often require selective conjugation or labeling of the N- and/or C-termini of peptides either through bottom up approaches or selective post-cleavage functionalization of specific residues after proteolytic digestion . For

The need for multicomponent gas standards for breath biomarker analysis

July 7, 2022
Author(s)
Kavita Jeerage, Jennifer Berry, Jacolin Murray, Cassie Goodman, Paulina Piotrowski, Christina Jones, Christina Cecelski, Jennifer Carney, Katrice Lippa, Tara Lovestead
Exhaled breath is a non-invasive, information-rich matrix with the potential to diagnose or monitor disease, including infectious disease. Despite significant effort dedicated to biomarker identification in case control studies, very few breath tests are

Computational Study of the Allosteric Effects of p5 on the CDK5-p25 Hyperactivity as Alternative Inhibitory Mechanisms in Neurodegeneration

June 30, 2022
Author(s)
Tejaswi Tammareddy, Walid Keyrouz, Ram D. Sriram, Harish C. Pant, Antonio Cardone, Jeffery B. Klauda
The cyclin-dependent kinase (CDK5) forms a stable complex with its activator p25, leading to the hyperphosphorylation of tau proteins and to the formation of plaques and tangles that are considered to be one of the typical causes of Alzheimer's disease (AD

Evidence that gecko setae are coated with an ordered nanometer-thin lipid film

June 9, 2022
Author(s)
Cherno Jaye, Daniel A. Fischer, Mette Rasmussen, Katinka Holler, Joe Baio, Stanislav Gorb, Tobias Weidner
Motivated by the fascination of gecko adhesion based on the fibrous setae at the tips of their toe pads and their potential for biomimetic applications, the adhesion mechanism has been studied in detail. While the mechanism has been shown to be based on

Reference Material 8376 Microbial Pathogen DNA Standards for Detection and Identification

June 1, 2022
Author(s)
Jason Kralj, Dieter Tourlousse, Monique Hunter, Erica Romsos, Blaza Toman, Peter Vallone, Scott Jackson
Reference Material (RM) 8376 is intended for NGS-based measurements quantitative to the chromosome. A unit of RM 8376 consists of 20 components (A-T, 19 bacteria and 1 human) each containing well-characterized DNA in 10 mmol/L Tris-HCl, 1 mmol/L EDTA pH 8
