resin by addition reaction; and R1 is a methyl or ethyl group), with water, the product (b) containing organosilicon compound polycondensates formed in the epoxy resin (a) and having a degree of polycondensation of 2 or higher, and which has a low viscosity at a room temperature (25掳 ...
Complex therapeutic protein analysis simplified with native MS An example would be the analysis of an IgG mixture of six therapeutic proteins with a range of glycosylation patterns; glycosylation is a key post...
Accurately predicting protein–ligand interactions is crucial for understanding cellular processes. We introduce SurfDock, a deep-learning method that addresses this challenge by integrating protein sequence, three-dimensional structural graphs and surfa
A photosensitive mixture that contains a photosensitive compound, for example, a photoinitiator or a diazo compound, and a reaction product of a polymer containing active hydrogen with an olefinically unsaturated compound represented by the formula ##STR1## wherein X and Y are the same or differe...
Auranofin (AF), a gold (I)-containing phosphine compound, is being investigated for oncological application as a repurposed drug. We show here that 4~5 µM AF induces paraptosis, a non-apoptotic cell death mode characterized by dilation of the endop
(Li) and oxygen combine to create lithium oxide (Li2O). Sometimes, a new compound might form when an element is exposed to an existing compound. For example, when pure elemental sodium (Na) is submerged into liquid water (H2O), a reaction occurs, resulting in the formation of sodium ...
Environmental factors, such as overcrowding, high levels of nitrogenous wastes, and low levels of dissolved oxygen are implicated as factors that may promote BGD in intensive culture operations; however, retrospective epidemiological studies indicate that specific management practices in hatcheries and ...
The 384-well format assay coupled with WST/1-mPMS was applied to high-throughput screening and evaluation of compound potency. The Michaelis constant (Km) value was assayed in a buffer at final volume of 40 µL (100 mM HEPES, pH 7.4;100 mM NaCl; 2 mM MgCl2; 0.1 mM DTT; 0.5 mM ...
There are no non-hormonal male contraceptives currently on the market despite decades of efforts toward the development of “male pills”. Here, we report that triptonide, a natural compound purified from the Chinese herb Tripterygium Wilfordii Hook F di
