The method disclosed by the invention comprises the following steps: preparing a low-molecular-weight heparin sodium solution by virtue of a sodium nitrite method at first, and then carrying out resin calcification on cation exchange resin by use of a calcium chloride solution, then carrying out ...
1e). This global signal intensity decrease in the β1-CT is consistent with a molecular weight increase upon formation of a ternary complex. In addition, the 1H–13C correlation spectra of β1-CT in the presence of both TLN1-F3 and ΔKIND2 (Fig. 1d and Extended Data Fig. 1c) ...
the original sludge loses weight due to the evaporation of moisture; when the temperature is in the range of 300–500 °C, the original and external sludge samples are due to fibers and some polymer compounds, etc. Difficult volatile organic compounds are decomposed to show weight loss101; Whe...
Ultra-High Molecular Weight Polyethylene (UHMWPE) represents the gold standard as an articulated counterpart to arthroplasty, because it combines superior wear resistance, excellent breakingstrengthand outstandingbiocompatibilityin comparison to other polymers. Originally, high-densitypolyethylene...
Samples were spiked with calcium chloride (final concentration 10 mM) and diluted to 480 μL with AMBIC before addition of 5 μg chymotrypsin (Promega, Madison, WI, USA) in 20 μL AMBIC. Samples were incubated overnight at 37 °C and the reaction was terminated by the addition of ...
We found that calcium chloride exerted a synergistic effect when added to reaction mixtures containing other cations. For example, simultaneous addition of 10 mM calcium chloride and 10 mM MgCl2 produced an increase in activity that was significantly higher than the total activity detected in the pre...
Effect of Hard Segment Molecular Weight on Dilute …:硬段分子量影响稀… 热度: PROBLEMS ON PERCENT COMPOSITION, EMPIRICAL FORMULA, AND MOLECULAR FORMULA 1. Calculate the formula or molecular mass for the following substances: Potassium sulfate sulfur dioxide Calcium hydroxide ...
Crystals were grown by hanging drop vapor diffusion in drops containing 2 μL of the protein solution mixed with 2 μL of 0.2–0.3 M magnesium acetate or calcium acetate, 20–30% (wt/vol) PEG 3350 equilibrated against 900 μL of the same solution. Crystals were transferred to 35% (wt/...
The invention relates to a process for the molecular weight increase/crosslinking of non-halogen-containing thermoplastic polymers, in which process a composition comprising a) a no
The present invention describes the production of high molecular weight unsaturated esters of polyhydric alcohols and their derivatives.
