In contrast to the flexible C-terminal region, the highly conserved fingerprint residues are located at the N-terminus of helix E and include a disulfide bond that locks the conformation of AB loop and helix E. Residues on this end of the helix bundle are more flexible than the central core but adopt well-defined structures in the crystal and in solution. Thus, structural differences on this end of the bundle are thought to influence the different receptor binding and biological properties of IFN-a and 1EN-/3.

The location of structurally important and conserved residues on the IL-10 and IFN-a scaffolds are shown as spheres and labeled. See Tables IV and V for equivalent residues in other IL-lOFMs or type I IFNs, respectively.

Latent Print Fingerprint residue that is not easily visible to the naked eye and must be treated, either physically or chemically, to be observed. 

An interesting and novel potential use of dendrimers has been described by Menzel and co-workers who have developed photoluminescent dendrimers for fingerprint detection [101]. Amine terminated PAMAM dendrimer nanocomposites with cadmium sulfide were synthesised by the addition of methanolic solutions of cadmium nitrate and sodium sulfide to a methanolic solution of the dendrimer. Amine terminated dendrimers were selected so that they could form amide bonds with the carboxylic acids abundant in fingerprint residues. When bound to the fingerprint residues, the dendrimer composites serve as photoluminescent markers that aid detection.
