7. Objective:To establish a method to determine relative molecular mass and distribution of hydroxyethyl starch 130/0.4 and sodium chloride injection by size exclusion chromatography. 目的:建立凝胶色谱法由多角度激光光散射检测器和示差折光检测器联用测定羟乙基淀粉130/0.4氯化钠注射液相对分子质量及分布的方...
Effects of low mol. wt. additives on the viscosity of cassava starch pastes were studied. Pastes were prepared at concn. of 5% cassava starch, and the additives tested were sodium sulphite, propyl gallate, ascorbic acid and glutathione. Sodium sulphate and sodium chloride were also tested to ...
1e,g). The opposing MST trends allowed us to distinguish the contributions of the talin–integrin and the kindlin–integrin binding site in titration experiments with the TLN1-F3–ΔKIND2 fusion protein with wild-type (WT) β1-CT (Fig. 3g). The experiment revealed that the titration of ...
Their toxicity was quantified by the EC50 values of each of these PILs towards HaCat cells, which are derived from human skin cells. Additional salts and solvents were used for comparison including DMSO, choline chloride, potassium nitrate, sodium acetate and ethanol to distinguish if the toxicity...
To test the ribosome binding ability of the RAC variants, 1 µg 80S ribosomes (wt or ES12∆10) were mixed with 0.8 µg RAC and incubated for 30 min at 30 °C to allow the formation of RAC–ribosome complexes. Unbound RAC was removed via centrifugation through a 25% (w/v) suc...
(WT-MetaD), we can accurately describe the intricate interfacial reactions and dynamics, thereby addressing the limitations of classical MD and static DFT calculations. We have demonstrated that the initial hydration of C3A commences with significant surface hydroxylation due to the pronounced ...
Molecular sieves have a pore size that is defined by the particular ion used in the preparation of the material – calcium aluminium silicate gives a pore size of 0.5 nm, whereas sodium aluminium silicate gives a pore size of approximately 1 nm. These are the two commonest molecular sieves;...
The epithelial cells of the gastrointestinal (GI) tract communicate with each other and with cells of other organs via a complex network of highly regulated movement of ions and biomolecules. The molecules ensure regulated activity of cells, tissues, and
Bars represent the mean value of n≥ 1 individual measurements. g, Non-reducing SDS–PAGE of WT OEP21 and OEP21-C109A (20 μM) in the absence (–) or presence (+) of oxidizing 1 mM Cu2+. d, dimer; m, monomer. a, d and g are representative of n≥ 2 independent ...
Six replicate populations of WT, ΔluxOU, and correspondinglacZ-tagged strains (arrayed in alternating fashion to monitor against population cross-contamination) ofV. campbellii(previouslyV. harveyi[32]) were passaged in M9 salt medium (Difco) with 2% sodium chloride supplemented with casamino acids...
