Some simple thin-layer chromatographic systems for the separation of purines and purine nucleosides.
Studies on nucleic acid metabolism often require the analytical separation of nucleic acid derivatives and are facilitated by chromatographic methods which are rapid and convenient. Column chromatography on ion exchange resins (1)) paper chromatography (2)) and paper electrophoresis (3) are among the methods used routinely for such separations. Even though these techniques have been employed wi...
متن کاملEffects of Microcrystalline Cellulose and Hydroxypropylmethyl Cellulose on the Properties of Dough and Flat Bread (Iranian Barbari Bread)
There are many reports on the application of different hydrocolloids in the production of leavened breads; most of which show positive effects on bread quality. However, there is little information to prove such effect on flat breads. The main aim of this study was to improve the quality of Barbari dough and bread (Iranian flat bread) in terms of texture, taste and general acceptability of fres...
متن کاملGreen synthesis of a typical chiral stationary phase of cellulose-tris(3, 5-dimethylphenylcarbamate)
BACKGROUND At present, the study on the homogeneous-phase derivatization of cellulose in ionic liquid is mainly focused on its acetylation. To the best of our knowledge, there has been no such report on the preparation of cellulose-tris(3,5-dimethylphenylcarbamate) (CDMPC) with ionic liquid 1-allyl-3-methyl-imidazolium chloride (AmimCl) so far. RESULTS With ionic liquid 1-allyl-3-methylimidaz...
متن کاملThe processive endocellulase CelF, a major component of the Clostridium cellulolyticum cellulosome: purification and characterization of the recombinant form.
The recombinant form of the cellulase CelF of Clostridium cellulolyticum, tagged by a C-terminal histine tail, was overproduced in Escherichia coli. The fusion protein was purified by affinity chromatography on a Ni-nitrilotriacetic acid column. The intact form of CelF (Mr, 79,000) was rapidly degraded at the C terminus, giving a shorter stable form, called truncated CelF (Mr, 71,000). Both the...
متن کاملIon-exchange in Analytical Chemistry: Problems and Prospects
An analysis is made of some of the practical problems of ion-exchange chromatography. A comparison is made with gas—liquid chromatography and this leads to the suggestion that improvements can be made in the monitoring system and in the selection of eluents for specific separations. The need for a general purpose gradient elution apparatus is stressed. Some theoretical aspects of several factor...
