Monoclonal antibodies (MAbs) previously shown to recognize distinct epitopes selectively expressed on the surface of some Mycoplasma hyorhinis strains were used to define two discrete sets of lipid-modified membrane surface proteins showing marked size variation within this species. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblot analysis of Triton X-114 phase-fractiona...
Although TroA (Tromp1) was initially reported to be a Treponema pallidum outer membrane protein with porin-like properties, subsequent studies have suggested that it actually is a periplasmic substrate-binding protein involved in the transport of metals across the treponemal cytoplasmic membrane. Here we conducted additional physicochemical studies to address the divergent viewpoints concerning...
One of the main challenges in proteomics lies in obtaining a high level of reproducible fractionation of the protein samples. Automated two-dimensional liquid phase fractionation (PF2D) system manufactured by Beckman Coulter provides a process well suited for proteome studies. However, the protein recovery efficiency of such system is low when a protocol recommended by the manufacturer is used ...
Succinate dehydrogenase (SDH) was solubilized from membranes of Mycobacterium phlei by Triton X-100 with a recovery of about 90%. The solubilized SDH was purified about 90-fold by Sephacryl S-300, DEAE-cellulose, hydroxylapatite, and isoelectric focusing in the presence of Triton X-100 with a 20% recovery. SDH was homogeneous, as determined by polyacrylamide gel electrophoresis in nondenaturing...
In this article cloud-point extraction (CPE) was used with chelating agent to extract uranium from aqueous solutions. The methodology used is based on the formation of metal complexes soluble in a micellar phase of surfactant. The metal ions complexes are then extracted into the surfactant-rich phase at a temperature above the cloud-point temperature. The effect of type of surfactants and ligan...
این پایان نامه در ابتدا به چگونگی اندازه گیری ضرایب نفوذ منفرد با استفاده از تکنیک pfg اسپکتروسکوپی nmr و تحلیل طیفها بوسیله برنامه core می پردازد و سپس با بدست آوردن ضرایب نفوذ منفرد اجزا سیستم به مطالعه سیستم سورفکتانهای triton x-100, ctab و sds می پردازد که نقاط cmc سورفکتانتهای ctab و triton x-100 بدست آمد و سپس مخلوط این دو سورفکتانت بررسی شد و وجود سینرجیسم...
Triton X-100 is widely but not universally used in NADPH-diaphorase histochemical staining. We investigated its effect on the staining and examined nitroblue diformazan (NBF) production under the influence of Triton X-100. Exposure of opossum esophagus, intestine, and colon tissues to Triton X-100 before staining enhanced staining of nerve cells and fibers and suppressed staining of non-neural ...
In this study the application of ZnO nanoparticles to UV photocatalytic degradation of nonionic surfactantTriton X-100 in aqueous media was investigated. The affecting factors on the photodegradation such as TritonX-100 initial concentration, nanocatalyst weight, pH, temperature and other parameters were studied anddescribed in details. The degradation rate was found to be strongly influenced b...
Proteoglycogen is the end product in the process of glycogen biogenesis. We have purified rabbit muscle proteoglycogen and studied the glucosyltransferase reactions catalyzed by its protein moiety, glycogenin, free or bound to the polysaccharide. The purification strategy involved dissolution of proteoglycogen and cosedimenting membrane vesicles in a Triton X-114/Triton X-45 mixture followed by...
