| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Conformational study of Z-Glu-OH and Z-Arg-OH: dispersion interactions versus conventional hydrogen bonding.[Pubmed:23095122]
J Phys Chem A. 2013 Feb 14;117(6):1216-27.
The gas-phase conformational preferences of the model dipeptides Z-Glu-OH and Z-Arg-OH have been studied in the low-temperature environment of a supersonic jet. IR-UV ion-dip spectra obtained using the free electron laser FELIX provide conformation-specific IR spectra, which in combination with density functional theory (DFT) allow us to determine the conformational structures of the peptides. Molecular dynamics modeling using simulated annealing generates a variety of low-energy structures, for which geometry optimization and frequency calculations are then performed using the B3LYP functional with the 6-311+G(d,p) basis set. By comparing experimental and theoretical IR spectra, three conformations for Z-Glu-OH and two for Z-Arg-OH have been identified. For three of the five structures, the dispersion interaction provides an important contribution to the stabilization, emphasizing the importance of these forces in small peptides. Therefore, dispersion-corrected DFT functionals (M05-2X and B97D) have also been employed in our theoretical analysis. Second-order Moller-Plesset perturbation theory (MP2) has been used as benchmark for the relative energies of the different conformational structures. Finally, we address the ongoing debate on the gas-phase structure of arginine by elucidating whether isolated arginine is canonical, tautomeric, or zwitterionic.
