IMAC [ 141 2.1. Pass solubilized material (about 45 ml) at a flow rate of 0.4 ml/min over Ni-NTA resin equilibrated with buffer A. 2.2. Wash Ni-NTA column at a flow rate of 0.4 ml/min with 120 ml of buffer A. 2.3. Elute N T R fusion protein at a flow rate of 0.2ml/min with 80ml of buffer B*. Combine peak fractions (1 3 ml) and add protease inhibitors. Save 1 ml for analysis. 2.4. Dilute remaini...
Previous uranium mining in the "Wismut" region in Germany enhanced environmental distribution of heavy metals and radionuclides. Carryover effects may now lead to contamination of locally produced foods. Compounds of "Wismut" origin are probably genotoxic via their irradiating components (radon) or by interacting directly with cellular macromolecules. To assess possible hazards, we investigated...
Pituitary adenylate cyclase‑activating polypeptide (PACAP) is a type of neuropeptide with multiple biological functions. However, it has a short half‑life period in the body, ~3 to 5 min, restricting its further development as a drug that can promote the recovery of nerve injury. In vitro and in vivo experiments have shown that PACAP can repair the epithelial cell on the surface of the injured ...
Removal of iron from biologically important ligands by desferrioxamine (DF), in vitro, is exceedingly slow because of a kinetic barrier. This kinetic barrier can be overcome by a variety of a small molecular weight anions, of which nitrilotriacetate (NTA) is a prototype. We explored the effect of NTA on DF iron mobilization in vivo. Iron mobilization was increased and the effect was synergistic.
Nanoparticle tracking analysis (NTA) was first applied to biologically active nanocomplexes to obtain concurrent information on their size, state of aggregation, concentration, and antigenic specificity in liquid. The subject of the NTA was an immunogenic complex (a candidate nanovaccine) comprised of spherical particles (SPs) generated by thermal remodeling of the tobacco mosaic virus and Rube...
گیاه‌پالایی یک روش برای پالایش فلزات سنگین از خاک است. استفاده از کلات‌کننده‌ها می‌تواند سبب افزایش کارایی گیاه‌پالایی گردد. هدف از انجام این پژوهش بررسی تأثیر کلات‌کننده نیتریلوتری استیک اسید (NTA) بر شاخص‌های رشدی و کارایی گیاه-پالایی گیاه ذرت در خاک‌های آلوده به کادمیوم تحت شرایط آبشویی بوده است. بدین منظور در گلخانه آزمایشی شامل سه سطح کادمیوم (صفر، 25 و 50 میلی‌گرم در کیلوگرم خاک) و NTA ب...
The El Niño–Southern Oscillation (ENSO) is known to influence the North Tropical Atlantic (NTA) sea surface temperature (SST) during its decaying spring, providing an essential source of NTA predictability. However, positive ENSO–NTA SST relationship absent boreal winter, impeding accurate anticipation wintertime fluctuations. We find that this absence mainly due different preconditions. Taking...
The rates of mineralization of nitrilotriacetic acid (NTA), 2,4-dichlorophenoxyacetic acid (2,4-D), p-nitrophenol, aniline, and isopropyl N-phenylcarbamate (IPC) at one or more concentrations ranging from 100 pg/ml to 1.0 microgram/ml were proportional to chemical concentrations in samples of three lakes. The rates at 100 pg of NTA, 2,4-D, p-nitrophenol, and aniline per ml in samples of one or ...
Recently, two types of TiO2 nanotube arrays (NTAs) (blue- and black-colored TiO2 NTAs), which are easily fabricated by electrochemical self-doping, have gained much attention due particularly to their enhanced capacitive and oxidant-generating properties. These enhanced electrochemical properties mean that they have potential as basic materials for energy and environmental applications, such as...
