SSCP Analysis of Point Mutations by Multi-Color Capillary Electrophoresis

November 1, 1999
Author(s)
K Hayashi, H M. Wenz, M Inazuka, T Tahira, Donald H. Atha
Virtually all methods for the detection of mutations (polymorphism or variant) rely on polymerase chain reaction (PCR). Direct sequence determination of a PCR product is the gold standard for identifying mutaions. However, the vast majority of the signal

In-situ Monitoring of Protein Unfolding/Structural States under Cold High-Pressure Stress

November 26, 2021
Author(s)
Diana Gomes, Susana C. Marujo Teixeira, Juscelino Leao, Vladimir Razinkov, Wei Qi, Miguel Rodrigues, Christopher Roberts
Biopharmaceutical formulations may be compromised by freezing, which has been attributed to protein conformational changes at a low temperature, and adsorption to ice−liquid interfaces. However, direct measurements of unfolding/conformational changes in

Solvent-cast 3D Printing of Biodegradable Polymer Scaffolds

October 22, 2021
Author(s)
John Tolbert, Diana Hammerstone, Nathaniel Yuchimiuk, Jonathan Seppala, Lesley Chow
… polymers like poly(caprolactone) (PCL), poly(lactic acid) (PLA), and poly(lactic-co-glycolic acid) (PLGA) that can degrade to permit new tissue formation …

Direct Measurement of Trace Polycyclic Aromatic Hydrocarbons in Diesel Fuel with 1H and 13C NMR Spectroscopy: Effect of PAH Content on Fuel Lubricity

June 17, 2015
Author(s)
Peter Y. Hsieh, Jason Widegren, Andrew Slifka, Andrew J. Hagen, Ronald A. Rorrer
Surface-active trace compounds present in diesel fuels protect pumps and injectors against premature wear through boundary lubrication. Due to the vast number of hydrocarbon compounds found in petroleum distillate fuels, it is difficult to measure the
