The reducing substances that can be oxidized by KMnO4 equal to the 1.015 mol/mL by oxalate, and positive ion, negative ion and neutral molecules in these were 7.84%, 64.16% and over 28.0%, respectively.
Methods SiRNAs(small interfering RNA, siRNA) for WT1 gene was designed and synthesized, then be transfected into breast cancer cells line MCF-7 by positive ion liposome Lipofectamine 2000. Transfect effiency was assessed by flow cytometry. Use RQ-PCR(Real-time Quantitative Polymerase Chain Reaction) to detect the expression of WT1 andβ-actin mRNA, and then screening the most effective siRNA. Expression of WT1 protein was detected by western blot.
Synthesis of hydrophobic association cationic starch and its flocculation application on containing algae water of Dianchi Lake
The hydrophobic formation cationic starch (PSOAMDA) was prepared from starch (St), octadecyl acrylate (OA), acrylamide (AM) and dimethyl diallyl ammonium chloride (DMDAAC) by means of inverse suspension polymerization with redox initiator.
91.3% and 69.2% obtained with the commercial cationic polyacrylamide (PAM-C).
The cationic ring-opening copolymerization of AMO with another oxetane-derived monomer, 3-(2-(2-(2-methoxyethylenoxy)ethylenoxy)ethylenoxy)-3'-methyloxetane (MEMO) was conducted in CH2Cl2 solution using BF3 · OEt2/1,4-butanediol as a co-initiator.
The state of the antioxidant complex of molluscan tissues under conditions of natural (spawning) and artificial (exposure to a cationic surfactant) oxidative stress was studied.
Analysis of statistical thermodynamic model for binary protein adsorption equilibria on cation exchange adsorbent
Seven pore water samples were analyzed for their anion (Cl-, SO42-, Br-, I-) contents, cation (Na, K, Ca, Mg) contents and trace element (Li, B, Sr, Ba, Rb, Mn) contents.
When the mercury chloride molecular axis is vertical to the surface, the Cl atom coordinates to the Ca2- cation and has a binding energy of 23.699 kJ/mol.
The Mn/Ce serial catalysts were characterized by Brunauer-Emmett-Teller (BET) analysis and the metal cation leaching was measured by inductively coupled plasma torch-atomic emission spectrometry (ICP-AES).
Saturation of zeolite with Ca2+ rather than Na+ favored the removal of both ammonium and phosphate because the cation exchange reaction by the NH4+ resulted in the release of Ca2+ into the solution and precipitation of Ca2+ with PO43- followed.
The assumption of the first kinetic order of heterogeneous loss of atoms provides for adequate agreement of the experimentally obtained and calculated values of E/N and of the density of positive ion flux to the surface of discharge tube.
A study is made of the interaction of an electron beam focused by a positive ion background with electromagnetic waves in a pasotron-a modern plasma microwave electronics device with long-term interaction in the ion focus regime.
It is shown that a positive ion is detected due to electron emission from the surface of a negatively charged wire, whereas a negative ion is detected due to electron detachment near a positively charged wire.
This effect is shown to be associated with a positive ion charge forming on the film.
Gas chromatography-mass spectrometry in the electron impact mode and thermospray liquid chromatography-mass spectrometry in the positive ion mode have been employed as confirmatory characterization techniques.
