Methods Recombinant Pla l 1.0101 was heterologously expressed in the E. coli strain Rosetta-gami B pLysS and purified using cation exchange and size exclusion chromatography. Natural Pla l 1 was obtained by pollen extraction and cation exchange chromatography. Physico-chemical properties of the purified proteins were analyzed in gel electrophoresis, mass spectrometry and circular dichroism. Usi...

Estimation of plasma catecholamine concentrations by "high-performance" liquid chromatography, although increasingly used, still presents difficulties. We describe a method for clean-up of plasma samples on cation-exchange resin before they are extracted with alumina. This procedure eliminates many of the interfering compounds often present in plasma extracts prepared with the alumina treatment...

in concentration of hydrogen peroxide, first, the solution should be quite pure, and then, it concentrate with methods such as vacuum distillation and cooling crystallization, because impurities in the hydrogen peroxide solution in high concentrations are causing decomposition of this substance; that is very dangerous. the purpose of this article is separation of chromium and magnesium cations ...

The regeneration processes of industry technological passivating baths electrochemical cadmium lines and galvanizing as an applied result two-chamber membrane cation-exchange devices researched. Actual industrial passivation zinc galvanic coatings anode chambers. cathode chamber contained sulfuric acid 1 % solution a titanium (BT-0). A window was cut in one the walls with RALEX®CM-PES 11-66 cat...

The application of electrochemical reactions in natural product synthesis has burgeoned in recent years. We herein report a formal synthesis of the complex and dimeric natural product kingianin A, which employs an electrochemically-mediated radical cation Diels-Alder cycloaddition as the key step.

Asking the question again: are cation exchange resins effective for the treatment of hyperkalemia? / auth.

This article presents the method of extraction-preconcentration of Lead, Cadmium, and Nickel ions from food samples using the Ghezeljeh montmorillonite nanoclay (Geleh-Sar-Shoor) as a new native adsorbent in batch single component systems. The extraction-preconcentration of heavy metals were carried out by applying the solid phase extraction (SPE) method followed by atomic abs...

A mixture of a carhoxylic acid type of cation exchange resin and a weakly basic anion exchange resin has been used successfully to control the edema of 42 patients wvith congestive heart failure andl the ascites of 14 patients with cirrhosis of the liver. Approximately one-third of the cation exchanger was supplied in the potassium cycle. Inclusion of the anion exchange resin resulted in a grea...
