OBJECTIVES Our previous study showed poor mechanical durability and nano-sized heterogeneities in cross-linked dentin adhesives cured in the presence of water. To further explore the relationship between nano-scale heterogeneities and the long-term mechanical properties of dentin adhesives, the properties of model dentin adhesives polymerized using(More)
Protein drugs have revolutionized the pharmaceutical industry, offering new treatments for serious diseases. Since the first recombinant protein drug, Eli Lilly's Humulin®, was approved 30 years ago (1), protein drugs have grown from esoteric specialty products to a major drug class. Of the 20 top selling drugs in the USA in the third quarter of 2012, nine(More)
Solid state amide hydrogen/deuterium exchange with mass spectrometric analysis (ssHDX-MS) was used to assess the conformation of myoglobin (Mb) in lyophilized formulations, and the results correlated with the extent of aggregation during storage. Mb was colyophilized with sucrose (1:1 or 1:8 w/w), mannitol (1:1 w/w), or NaCl (1:1 w/w) or in the absence of(More)
Aggregation is common in protein drug manufacture, and while the effects of protein particulates are under investigation, many techniques applicable for their characterization have been recently developed. Among the methods available to characterize and quantify protein aggregates, none is applicable over the full size range and different methods often give(More)
