In this work, Phosphotungstic Acid modified Carbon Paste Electrode (PWA-CPE) is used as a substrate for electro-polymerization of o-Anisidine (OA). Also, Triton X-100 (TX-100) surfactant is used as an additive for electrochemical polymerization of OA onto the PWA-CPE, which is investigated as a novel matrix for dispersion of nickel species. The prepared electrodes are characterized by...

General Experimental Procedures: Egg phosphatidylcholine (ePC) and routine chemicals were obtained from Sigma Chemical Co. SM-2 Bio-beads were purchased from Bio-Rad Laboratories. ULTROL grade Triton X-100 was from Roche Molecular Biochemicals. 1-acyl-2-C6-NBD-PC (NBD-PC) was from Avanti Polar Lipids. Salt-washed endoplasmic reticulum (SWER) was prepared from a rat liver homogenate as previousl...

Photosystem II reaction centers comprised of the Dl, D2 and cytochrome b-559 polypeptides were isolated from welldefined oxygen-evolving reaction center preparations using either a combination of LiClO, and dodecyhnaltoside, or Triton X-100 alone. Yields of chlorophyll and cytochrome b-559 for both preparative methods were compared, and pigment contents were compared based on 2.0 b-559 per reac...

cobalt oxide (co3o4) nanoparticleshave been synthesized by hydrothermal method using mixture of cobalt(ii)chloride, triton x-100 and koh in an autoclave at 180 °c for 6 h followed by heating at 400 ºc for 3 h in air. the product have been characterized by fourier transform infrared (ft-ir), uv-vis spectroscopy, powder x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission ...

PURPOSE Primary open-angle glaucoma (POAG) is associated with a decreased content of hyaluronan in the trabecular meshwork and in the juxtacanalicular connective tissue. In this study, the authors examined selected regions of the anterior segment to localize and determine the content of CD44H, a transmembrane multifunctional glycoprotein and the principal receptor of hyaluronan. METHODS Secti...

In this work, the lipase from Pyrococcus furiosus encoded by ORF PF2001 was expressed with a fusion protein (thioredoxin) in Escherichia coli. The purified enzymes with the thioredoxin tag (TRX-PF2001Δ60) and without the thioredoxin tag (PF2001Δ60) were characterized, and various influences of Triton X-100 were determined. The optimal temperature for both enzymes was 80°C. Although the thioredo...

Mixtures of alkyltrimethylammonium bromide (CnTAB, n=12, 14, 16, 18) and Triton X-100 were studied at a range of mole fractions of ionic surfactant per nonionic surfactant. For each mixture, the cmc obtained from surface tension measurements differed from that obtained using potentiometry. The behavior of these mixed-surfactant systems showed three different regions with increasing total surfac...

The lipophilic protein moieties of human low density lipoprotein, Semliii Forest virus envelope, and human erythrocyte stroma were obtained lipid-free with the use of sodium deoxycholate treatment and gel filtration in deoxycholatecontaining media. Detergent binding was determined by subjecting the proteins to gel filtration in the presence of micellar concentrations of radioactive deoxycholate...
