Bazı protein ve enzim çözeltilerinde NMR rölaksasyon zamanlarını modüle eden ilgi zamanlarının T1/T2 oranı kullanımı yoluyla belirlenmesi
Zengin, Bilgin (2016)Bu çalışmada, Hemoglobin ve üç enzim (Pepsin, Proteaz ve -chymotrypsin) çözeltisinin H2O’ daki 1/T1 (spin-örgü) ve 1/T2 (spin-spin) rölaksasyon oranları 64 MHz (1.5 Tesla) MR pektrometresi kullanılarak ... -
Elimination of Radiation Damping Effects from the NMR Relaxation Curves of H2O/D2O Mixtures Containing Protein and Ions
Zengin, Bilgin; Koylu, Mehmet Zafer; Korunur, Sibel; Yilmaz, Ali (Physical Soc Republic China, 2013)In this work the T-1 and T-2 curves of H2O/D2O mixtures were obtained for several fractions of H2O and also for different amounts of albumin and manganese. The experiments were carried out with a 400 MHz proton NMR ... -
The Examination of a Variety of Different Ions Added to the Crown Ether Derivatives with High Field NMR Spectrometer
Askin, Muzaffer; Zengin, Bilgin; Korunur, Sibel; Kor, Harun; Koylu, M. Zafer (Maik Nauka/Interperiodica/Springer, 2017)The current study involves the measurements of T-1 relaxation time of complexes three different crown ethers (4-aminobenzo-15-Crown-5, 1-Aza-18-Crown-6, 1-Aza-15-Crown-5) and two different ions sodium perchlorate (NaClO4), ... -
Observation of Triplet Traces Obtained with Inversion Recovery Method in Both Residual Water- and H2O/D2O-Albumin Mixture by Using 400 MHz Proton NMR
Yilmaz, Ali; Zengin, Bilgin; Korunur, Sibel (Asian Journal Of Chemistry, 2013)NMR studies involving H2O/D2O mixtures are mainly based on a single spectrum of water. However, some recent papers have revealed the presence of an HDO triplet in H2O/D2O, which is caused by the splittings of H2O signal ...
