Mycobacterium &megmati at a concentration of 1: 20,000 and Myco. phlei at 1:10,000 but was completely inactive against an unidentified species of Mycobacterium not listed in Table 1. Fusein-thioglycollic acid. The results obtained. are summarized in Table 2. They indicate that, in general, the conversion of fuscin into its thioglycollic acid derivative caused a remarkably small change in its an...

Three chelating ion-exchange resins based on macroreticular polyacrylonitrile-divinylbenzene copolymers with thioglycollic acid and cysteine as functional groups have been tested for separation of molybdenum(VI) and tungsten(VI). On a short column of the thioglycollic acid resin, molybdenum(VI) and tungsten(VI) can be selectively sorbed from pH-4.3 acetate buffer and eluted with 2M hydrochloric...

A method is described for the estimation of adrenaline and noradrenaline in a 5 to 10 ml plasma sample.A batch technique of adsorption and elution from alumina is used and the final estimation is carried out using an automated fluorimetric technique based on the trihydroxyindole method. Fluorescence is stabilized first by thioglycollic acid to give noradrenaline concentrations only and then by ...

the comparison of growth processes and fluorescent properties of cdznte semiconductor quantum dots that are synthesized in different concentrations of zn2+ in water are discussed in this paper. the samples are characterized through absorbtion (uv) and photoluminescence spectra (pl). the results show that when the reaction time is prolonged, the absorption peak and fluorescent emission peak pres...

Treatment of wool with aqueous alkaline thioglycollic acid converts 65% of it into soluble fragments, which are insoluble at pH 4.6 and aggregate spontaneously and irreversibly on storage. Polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulphate shows that the soluble protein consists mainly of two components. The calibration curves for molecular weightsjelectrophoretic mob...
