The interaction of La3+ complexes of DOTA/DTPA-glycoconjugates with the RCA120 ...
Teixeira, João M. C.; Dias, David M.; Cañada, Javier; Martins, J. A. R.; André, João P.; Jiménez-Barbero, Jesús; Geraldes, Carlos F. G. C.The study of ligand-receptor interactions using high resolution NMR techniques, namely the Saturation Transfer Difference (STD), is presented for the recognition process between La(III) complexes of DOTA mono(amide) and DTPA bis(amide) glycoconjugates and the galactose specific lectin Ricinus Communis agglutinin (RCA120). This new class of Gd(III)-based potential targeted MRI contrast agents (CAs), bearing one ...
Polymerization of lignosulfonates by the laccase-HBT (1-hydroxybenzotriazole) s...
Prasetyo, E. N.; Kudanga, T.; Østergaard, L.; Rencoret, J.; Gutiérrez, A.; Río, J. C. del; Santos, J. I.; Nieto, L.; Jiménez-Barbero, JesúsThe ability of laccases from Trametes villosa (TvL), Myceliophthora thermophila (MtL), Trametes hirsuta (ThL) and Bacillus subtilis (BsL) to improve the dispersion properties of calcium lignosulfonates 398 in the presence of HBT as a mediator was investigated. Size exclusion chromatography showed an extensive increase in molecular weight of the samples incubated with TvL and ThL by 107% and 572% from 28400 Da a...
