The fingerprint region of a protein consists of all the amide proton to alpha proton correlations. Typically these are the starting point for assigning spin-systems in homonuclear assignment. They are picked in the COSY spectrum.
Below the fingerprint region has been selected for expansion by click-dragging in the DQF-COSY spectrum of a 36 residue protein.
After releasing mouse, HomoScope zooms into the fingerprint region:
