A CONVENIENT METHOD FOR THE FORMOL TITRATION

The Journal of General Physiology, 1926
The formol titration, as described by Srrensen, 1 has been most useful in the determination of amino-acids and especially in following the course of hydrolysis of proteins.

Independent Ion Migration in Suspensions of Strongly Interacting Charged Colloidal Spheres

, 2000
We report on sytematic measurements of the low frequency conductivity in aequous supensions of highly charged colloidal spheres. System preparation in a closed tubing system results in precisely controlled number densities between 1E16/m3 and 1E19/m^3 ...

The removal of thermally aged films of triacylglycerides by surfactant solutions [PDF]

, 2013
Thermal ageing of triacylglycerides (TAG) at high temperatures produces films which resist removal using aqueous surfactant solutions. We used a mass loss method to investigate the removal of thermally aged TAG films from hard surfaces using aqueous ...

Quantitative high-throughput screening: a titration-based approach that efficiently identifies biological activities in large chemical libraries.

Proceedings of the National Academy of Sciences of the United States of America, 2006
High-throughput screening (HTS) of chemical compounds to identify modulators of molecular targets is a mainstay of pharmaceutical development. Increasingly, HTS is being used to identify chemical probes of gene, pathway, and cell functions, with the ...

The sulphur and chlorine contents of grass and maize silage

Acta Agriculturae Slovenica, 2001
In seven defined samples of grass and in six samples of maize silage the contents of sulphur and chlorine were determined by two analytical procedures: both elements with X-ray fluorescence spectrometry (XRF), sulphur separately with inductively coupled ...

A TITRATION METHOD FOR BLOOD FAT

, 1929
The basic idea of the method given in this paper is to isolate the fatty acids and titrate them. The blood is extracted with alcohol and ether, the extract saponified, the fatty acids separated, filtered, washed, dissolved in alcohol, and titrated with ...

Protein sequestration generates a flexible ultrasensitive response in a genetic network

Molecular Systems Biology, 2009
Ultrasensitive responses are crucial for cellular regulation. Protein sequestration, where an active protein is bound in an inactive complex by an inhibitor, can potentially generate ultrasensitivity. Here, in a synthetic genetic circuit in budding yeast,

Direct Analyses of Beer Macromolecular Complexes by Means of a New Differential Nephelometric Titration Method.

Kvasný průmysl, 2002
A new method of analyses of beer and intermediates macromolecular complexes - Differential Nephelometric Titration (DNT) was developed. The method was analytically evaluated in various protein and PVP model solutions and their mixtures by titration with ...
