Method for the preselection of drugs for protein misfolding diseases

The invention provides a method that gives direct information about the intervention of a potential drug on the secondary structure distribution of a targetbiomolecule, i.e., for a disease with misfolded protein, such as neurodegenerative diseases in a complex body fluid. The secondary structural change is monitored by vibrational spectroscopy. The method can be applied for prescreening of drug candidates for targeting of specific biomolecules. The effect of the drug on the secondary structure distribution is monitored label-free in real time and provides thereby direct information about the efficacy of the potential drug.

PROGNOSIS METHOD FOR BLOOD DISORDERS

A method for determining the risk of developing a blood disorder, which includes the steps of: exposing a biological sample from an individual to radiation to obtain a spectrum characteristic of the sample, the spectrum being processed in order to obtain a spectral signature; comparing the spectral signature obtained with one or more reference spectral signatures; and concluding, if the spectral signature of the individual is significantly different from control spectral signatures, that the individual is likely to develop a blood disorder, and, if not, that the individual is not likely to develop a blood disorder.
