Hydration of fibrinogen, fibrin, and fibrin degradation product (FDP) as estimated by

Hydration of fibrinogen, fibrin, and fibrin degradation product (FDP) as estimated by nuclear magnetic resonance (NMR) spectroscopy.

Blood Coagul Fibrinolysis. 1991 Apr;2(2):243-9

Authors: Tanaka Y, Nakaya S, Yoshioka Y, Yoshida Y, Hanaoka H, Kawamura R, Yasuda N

The relaxation times (T1 and T2) of water proton in nuclear magnetic resonance (NMR) were measured with solutions containing bovine fibrinogen (Fbg), fibrin degradation products (FDP) and with fibrin-gel (Gel), at varying protein concentrations (0.7-70 mg/ml). Both T1 and T2 declined exponentially with increasing protein concentration. At a protein concentration of 35 mg/ml, the T1 of Fbg, Gel and FDP were 2.32, 2.12 and 2.82 s and the T2 values were 0.35, 0.17 and 0.70, respectively. The relaxation times for the control samples (0.2 M borate buffer) were 3.41 (T1) and 2.28 (T2). When the relaxation rates (the inverse of T1 and T2), R1 and R2 were plotted against the protein concentration, there were positive linear correlations between them. Using the slopes of the plots, the hydration value of each protein was calculated. The hydration value (g of H2O/g of protein) was 0.24 for Fbg, 0.34 for Gel and 0.14 for FDP.

[Question from NMRWiki Q&A forum] How to study polymer degradation by gamma and X-Ray radiation? How to study polymer degradation by gamma and X-Ray radiation? Hi, I was asked to study polyethylene degradated by gamma and Xrays. I planed to measure relaxations rates, but which one is the most relevant to highlight chain degradation? T1, T2, but on 1H or 13C? By reading some articles, I feel T2 is not very interesting, right? T1rho experiments seems to give good results, I have found 2 sequences in Bruker's library, T1rhoX (CP step then variable length spin lock pulse on 13C channel) and T1rhoH (CP step then variable length spin lock pulse on 1H channel), and there is also the more...	nmrlearner	News from other NMR forums	0	03-16-2011 06:24 PM

[Question from NMRWiki Q&A forum] Examples of protein degradation eg HSQC? Examples of protein degradation eg HSQC? Anyone know any websites or papers that show protein degradation in an HSQC for example? I wanted to know what to look for in old samples when I have them. Either that, or could someone put one up on the wiki for me to look at? Check if somebody has answered this question on NMRWiki QA forum	nmrlearner	News from other NMR forums	0	08-22-2010 02:30 AM
