given the importance of theology and best ways of knowing it in the islamic culture, this article is intended to examine the method of self-knowledge according to the ḥadīth, man ‘arafa nafsa faqad ‘arafa rabba (he who knows himself knows his lord) from the viewpoint of the shī‘a scholars and try to recognize the components of this noble ḥadīth by way of analysis and examine its different exper...

The polar flagellum of Vibrio alginolyticus is rotated by the sodium motor. The stator unit of the sodium motor consists of four different proteins: PomA, PomB, MotX and MotY. MotX and MotY, which are unique components of the sodium motor, form the T-ring structure attached to the LP ring in the periplasmic space. MotY has a putative peptidoglycan-binding motif in its C-terminal region and MotX...

The recombinant expression of soluble proteins in Escherichia coli continues to be a major bottleneck in structural genomics. The establishment of reliable protocols for the performance of small-scale expression and solubility testing is an essential component of structural genomic pipelines. The SSGCID Protein Production Group at the University of Washington (UW-PPG) has developed a high-throu...

BACKGROUND Functional Genomics, the systematic characterisation of the functions of an organism's genes, includes the study of the gene products, the proteins. Such studies require methods to express and purify these proteins in a parallel, time and cost effective manner. RESULTS We developed a method for parallel expression and purification of recombinant proteins with a hexahistidine tag (H...

A practically simple top-down process for the exfoliation of graphene (GN) and few-layer graphene (FLG) from graphite is described. We have discovered that a biocompatible amphiphilic pyrene-based hexahistidine peptide is able to exfoliate, functionalize, and dissolve few layer graphene flakes in pure water under exceptionally mild, sustainable and virtually innocuous low intensity cavitation c...

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...

Hikmah is an infinitive consequent from the Arabic root "hkm" and means deep valuable knowledge, wisdom, unseen cause. "to make a fair judgment, to know, understand, avoid, prevent persecution" feature that prevents hinders people cruelty death. According Imam Maturidi, hikmah ability distinguish (fiqh) between right incorrect, truth falsehood. Therefore, it reason attain many good both in worl...

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.
