Many proteins that accumulate in the form of insoluble aggregates when they are overproduced in Escherichia coli can be rendered soluble by fusing them to E. coli maltose binding protein (MBP), and this will often enable them to fold in to their biologically active conformations. Yet, although it is an excellent solubility enhancer, MBP is not a particularly good affinity tag for protein purifi...
tennessee williams (1911-1983), the modern american dramatist, had his own unique school of dramaturgy. the dramas which he depicted are populated by characters who are lonely, desperate, in anxiety, alienated and in one word lost. they face challenges which they may overcome or not, through the choices they make. all these moods and conditions are clearly seen and explained in the theory of ex...
A surface plasmon resonance imaging-based Ni(2+)-iminodiacetic acid-coated gold chip system was developed to enable specific detection of a hexahistidine-tagged recombinant protein in crude extracts or in column chromatography fractions. This system is especially advantageous for high-throughput analysis of multiple proteins.
Fluorescent probes are essential for the exploration of protein function, detection of molecular interactions, and conformational changes. The nitrilotriacetic acid derivatives of different chromophores were successfully used for site-selective noncovalent fluorescence labeling of histidine-tagged proteins. All of them, however, suffer from the same drawback--loss of the fluorescence upon bindi...
Affinity tags have become powerful tools from basic biological research to structural and functional proteomics. They were widely used to facilitate the purification and detection of proteins of interest, as well as the separation of protein complexes. Here, we mainly discuss the benefits and drawbacks of several affinity or epitope tags frequently used, including hexahistidine tag, FLAG tag, S...
in chapter 1, charactrizations of fragmentability, which are obtained by namioka (37), ribarska (45) and kenderov-moors (32), are given. also the connection between fragmentability and its variants and other topics in banach spaces such as analytic space, the radone-nikodym property, differentiability of convex functions, kadec renorming are discussed. in chapter 2, we use game characterization...
Sayyed Esmaeil Jorjani, (1042-1137) great Iranian scientist and physician who was born in Gorgan is very famous became of his medical writings in Farsi. His famous book named Zakhireh Kharazmshahi was translated into several languages at that time. In addition to his scientific works, Jorjani wrote several handbooks in medicine, in Farsi and in Arabic, for scientists and for the general public....
this thesis is a study on insurance fraud in iran automobile insurance industry and explores the usage of expert linkage between un-supervised clustering and analytical hierarchy process(ahp), and renders the findings from applying these algorithms for automobile insurance claim fraud detection. the expert linkage determination objective function plan provides us with a way to determine whi...

Scientific personality of Ibn al-Walid and his effect on succeeding scholars indicate of his prominent status and imply researchers’ need to overview and investigate his points of view. The present article is an introduction of Muhammad Ibn al-Hasan Ibn al-Walid and his works and a report of his perspectives in different issues. Employing a library method and descriptive-analytic approach, the ...
