A procedure for the determination of proteolytic activity [PDF]

, 1950
The difficulties introduced by the desire to maintain a constant pH during an enzyme-catalyzed hydrolysis of peptide-like substrates and at the same time to determine the extent of hydrolysis by an acid-base titration have been pointed out (1), but to ...

Simulation of weak polyelectrolytes: A comparison between the constant pH and the reaction ensemble method

, 2017
The reaction ensemble and the constant pH method are well-known chemical equilibrium approaches to simulate protonation and deprotonation reactions in classical molecular dynamics and Monte Carlo simulations.

MNase titration reveals differences between nucleosome occupancy and chromatin accessibility

Nature Communications, 2016
Chromatin accessibility plays a fundamental role in gene regulation. Nucleosome placement, usually measured by quantifying protection of DNA from enzymatic digestion, can regulate accessibility. We introduce a metric that uses micrococcal nuclease (MNase)

Dynamics of Different Buffer Systems in Slurries Based on Time and Temperature of Storage and Their Visualization by a New Mathematical Tool

Animals, 2020
Slurry treatments such as acidification and alkalization have proven to be promising solutions to reduce gaseous emission produced by farm animals. The optimization of these technologies requires detailed knowledge of how and to what extent the buffer ...

Exploiting the dynamic properties of FET-based chemical sensors [PDF]

, 1989
After a long period of mainly static application of ISFETS, other more sophisticated applications are being developed, based on the exploitation of the dynamic properties of ISFETS. Examples are the use of flow-through cells with sample injection and the

Water solubility in aluminosilicate melts of haplogranite composition at 2 kbar [PDF]

, 1992
The compositional dependence of H2O solubility was investigated at 2 kbar and 800°C in haplogranite melts (system SiO2---1bNaAlSi3O8---1bKAlSi3O8 or Qz---1bAb---1bOr).

Porphyra-334 Isolated from the Marine Algae Bangia atropurpurea: Conformational Performance for Energy Conversion

Marine Drugs, 2014
Prophyra-334 (p-334) may play a role of energy transfer under an uncertain mechanism, and we speculate the possible model. Via 1D and 2D NMR experiments, it was simulated the correlation between dissociation and conformation of p-334.

Amperometric Titrations

Transactions of The Electrochemical Society, 1940
In amperometric titrations the current passing through the titration cell is measured. These titrations require very little time and are applicable to very dilute solutions. Characteristic current‐voltage curves are shown. It is expected that amperometric titrations will find at least as extensive application as potentiometric titrations do now in ...

Rapid Field Assay for Pineapple Fruit Acidity

HortTechnology, 2020
The sugar-to-acid ratio of pineapple (Ananas comosus L.) contributes toward giving the fruit its unique flavor. This ratio is an important indicator of both commercial and organoleptic ripeness, and it is useful in determining a harvest date. Citric acid
