Aim: This study aimed to generate an improved method of protein extraction and purifi-cation from plant tissues containing very high amounts of phenolic compounds and other interfer-ing biomolecules. Background: Protein extraction at proteomic studies on some plant species, including conifers, is challenging, and the yield and quality are unpredictable. Objective: Two popular protocols were combined with each other to construct a novel one with en-hanced abilities to produce higher purity of samples compatible for high precision molecular sys-tems and analysis. Methods: The new method was compared with the other two for their efficiencies in classical SD-S-PAGE, 2-DE and capillary chromatography applications. Results: All three methods were comparable in SDS-PAGE procedure; however, only the new method created acceptable gel images in 2-DE. Bioanalyzer results, also, demonstrated that the new method provided protein samples pure enough to be used in capillary chromatography with 2 times more peaks in electropherograms with lower noise and higher total relative protein concentra-tions closest to the applied amount. Conclusion: The new combined method is a successful alternative for plant proteomicists with higher yield and quality of proteins from recalcitrant tissues. Other: The new method could be preferred, especially, for high-tech, sensitive proteomic analysis.

The Synthesis of 6- and 7- membered heterocyclic ring systems fused to pyridine ring Dinçoflaz, Yasemin; Balcı, Metin; Department of Chemistry (2013) The synthesis of the nitrogen containing heterocyclic compounds is one of the leading research areas throughout the organic chemistry due to their significant activities in biological systems. Among the various biologically active molecules, pyridine-fused ring systems are of prime importance on the grounds of their proven clinical roles. The coupling reactions with 6-membered heterocyclic compounds and diazepines gave rise to new pharmalogical compounds in recent years. Therefore, our object was the synthe...
A high-throughput microfluidic rare cell enrichment system based on dielectrophoresis and filtering Ozkayar, Gurhan; Yalcin, Yagmur Demircan; Ozgur, Ebru; Gündüz, Ufuk; Külah, Haluk (2016-05-27) In this study, a MEMS-based microfluidic device combining DEP-based cell manipulation with size-based filtration for the enrichment of CTCs from blood with high-throughput was developed. Positive-DEP (pDEP) force and the hydrodynamic force have been used to fine-tune the cell movement over the planar electrodes (sliding) at a high flow rate (30 mu l/min). While smaller sized RBCs passed through the gaps and were directed to the waste channels, cancer cells (K562 cells) were filtered and directed to the canc...
A Novel Amperometric Glutamate Biosensor Based on Glutamate Oxidase Adsorbed on Silicalite Soldatkina, O. V.; Soldatkin, O. O.; Kasap, B. Ozansoy; Kucherenko, D. Yu.; Kucherenko, I. S.; Akata Kurç, Burcu; Dzyadevych, S. V. (2017-04-07) In this work, we developed a new amperometric biosensor for glutamate detection using a typical method of glutamate oxidase (GlOx) immobilization via adsorption on silicalite particles. The disc platinum electrode (d = 0.4 mm) was used as the amperometric sensor. The procedure of biosensor preparation was optimized. The main parameters of modifying amperometric transducers with a silicalite layer were determined along with the procedure of GlOx adsorption on this layer. The biosensors based on GlOx adsorbed...
Investigation of bioreactor operation conditions for serine alkaline protease production by Bacillus subtilis Özdemir, Elif; Çalık, Pınar; Department of Chemical Engineering (2003) In this study, complex medium was designed for increasing serine alkaline protease (SAP) production by recombinant Bacillus sp. In this context, the effects of glucose, sucrose, inorganic nitrogen source, casein, defatted soybean, and molasses and their concerted effects were investigated in agitation (N=200 min"1) and heating rate (T=37°C) controlled laboratory scale bioreactors. For this purpose, experiments were started by microorganism selection. It was found that, most suitable microorganism for comple...
A novel urea conductometric biosensor based on zeolite immobilized urease Kirdeciler, Salih Kaan; Soy, Esin; Öztürk, Seçkin; Kucherenko, Ivan; Soldatkin, Oleksandr; Dzyadevych, Sergei; Akata Kurç, Burcu (2011-09-15) A new approach was developed for urea determination where a thin film of silicalite and zeolite Beta deposited onto gold electrodes of a conductometric biosensor was used to immobilize the enzyme. Biosensor responses, operational and storage stabilities were compared with results obtained from the standard membrane methods for the same measurements. For this purpose, different surface modification techniques, which are simply named as Zeolite Membrane Transducers (ZMTs) and Zeolite Coated Transducers (ZCTs)...
