Colorimetric Determination of the Amounts Types of the Guinea Pig.'
H E melanin pigments of mammals fall into two major categories, the T darker pigments or eumelanins and the orange yellow pigments or phaeomelanins. These presumably differ qualitatively although the exact chemistry 01 the melanins is not yet known. The hairs of wild cavies and of the so-called agouti variety of the guinea pig are predominantly eumelanic but have a phaeomelanic subterminal band...
متن کاملDevelopment of An Immobilized Enzyme Electrode for the Determination of Sulfite Ion
An enzyme electrode was developed using the enzyme sulfite oxidase (EC1.8.3.1) immobilized onto pig intestine. Hydrogen peroxide produced was monitored amperometrically. All experimental parameters such as pH, temperature, buffer constituent concentration, were thoroughly investigated and optimized when appropriate. The response to sulfite concentration was linear in the range 5.2´...
متن کاملColorimetric and fluorescent determination of sulfide and sulfite with kinetic discrimination.
Two fluorescent probes, m-PSP and p-PSP , for sulfite and/or sulfide were constructed by connecting a pyridinium ion to a coumarin fluorophore through an α,β-unsaturated ketone. The presence of the pyridinium salt promoted the nucleophilic addition of sulfite and sulfide to the α,β-unsaturated ketone, which could be visualized by dramatic changes in the solution's color and fluorescence intensi...
متن کاملA Colorimetric Method for Determining the Hydrogen Ion Concentration of Small Amounts of Fluid
The importance of the maintenance of the state of neutrality in practically all vital phenomena has become well recognized through the efforts of Sijrensen (l), Michaelis and his collaborators (2), Henderson (3), Clark (4), and nutierous others. The methods devised by them require the use of a considerable amount of fluid. While this fact is not a disadvantage in most types of investigation in ...
