Davey, C. A., Sargent, D. F., Luger, K., Maeder, A. W. & Richmond, T. J. Solvent mediated interactions in the structure of the nucleosome core particle at 1.9 Å resolution.
By comparing the spectral observations of DYMDAP with two control compounds DYMP and DYMDAB the proton transfer process is assigned to be due to solvent mediated and the proton transfer process is enhanced by the presence of charge transfer moiety.
However, the finding of key water molecules involved in the hu3S193 interaction with Ley supports the conclusion that solvent mediates the rigid conformational properties of this carbohydrate epitope and is important for antibody recognition.
The gels are responsive to temperature, pH, and ethanol solvent, which mediate the stability of the hydrophobic associations and even lead to gel-to-sol transition.
Coupland et al. subsequently proposed that samples for prolonged transport be fixated with HOPE solution (Herpes-glutamic acid buffer mediated Organic solvent Protection Effect) improved the quality of cytomorphology and immunocytology with reduced artefacts when compared to unfixed vitreous specimens [ 97].
Forty-eight hours post infection, mouse liver samples were fixed in HOPE Solution I (Hepes Glutamic Acid buffer mediated organic Solvent Protection effect; DCS, Hamburg) and were embedded in paraffin.
There is a great need to develop clean, nontoxic chemicals and environmentally benign solvents and renewable materials mediated synthesis method; thus a biological mediated synthesis of nanoparticles has received significant consideration in the last decade [ 8].
The optimized HOPE(Hepes-Glutamic acid buffer mediated Organic solvent Protection Effect) fixing technique allows us to preserve and extract high molecular weight DNA and RNA of >20 kbp suitable for downstream applications, such as PCR and RT-PCRfrom HOPE-fixed, paraffin-embedded tissues that are up to 5 years old.
On the other hand, a generous threshold allows to take indirect long-distance interactions into account, e.g. those mediated by solvent molecules.
In the molybdenum/tungsten storage protein (MoSto) from Azotobacter vinelandii networks of hydrogen bonds around different POM molecules were found, where the POM protein interactions are partially mediated by solvent molecules (Fig. 3A) [50,51].
The recently introduced Hepes-glutamic acid-buffer mediated Organic solvent Protection Effect (HOPE) is a promising alternative, which might have the potential to unite the benefits of FFPE and fresh-frozen specimen.
