Abstract:
In this case report, we describe the possibility of using ninhydrin-dyed fingerprints as a DNA source for STR typing. Preliminary tests prove that ninhydrin-dyed material still can be useful for STR typing. The case material consisted of seven ninhydrin-labeled latent fingerprints found at a murder crime site, which could not be typed in a classical manner. We were able to swap DNA from the ninhydrin-treated areas and successfully use it for STR typing.

Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...
