متن کاملThe Determination of Acetone
In the determination of P-oxybutyric acid through oxidation to acetone by the Shaffer bichromate method’ with subsequent estimation of the acetone by Messinger’s iodimetric titration,” difficulty was experienced in obtaining the t,heoretical amount of acetone from known amounts of pure P-oxybutyric acid. It was suspected that either the Messinger titration was inaccurate or that the acetone was...
متن کاملReuse of Acetone In
Plastination, developed by Gunther von Hagens in 1977 is described as a technique to preserve bodies or body parts in anatomy. During this process, the water is replaced by certain plastics that can be easily touched and do not cause decay, and even retain most properties of the original sample. Plastination is therefore, been proved to be very useful in anatomy as well as serving as models in ...
متن کاملcomparison of three routine protein precipitation methods: acetone, tca/acetone wash and tca/acetone.
the aim of this study was to compare three routine precipitation methods, including: acetone, tca/acetone wash and tca/acetone. 30 plasma samples were precipitated using above mentioned three methods. pellets were dissolved in rehydration solution and protein quantification was done for this solution. according to statistical analysis using spss ver 16.0 software and one-way anova test, the pro...
متن کاملFlash photolysis of caged compounds
Photolabile ‘caged’ compounds are biologically inert precursors of active molecules, which when irradiated with a pulse of light free the active species at its site of action (see Fig. 1). Speed is the principal advantage offered by these probes; photochemical reactions can be very fast, with release of the active species often complete within a millisecond. The method can thus be used to study...
