Abstract

We generally use luminal (LM) and leucomalachite green (LMG) in presumptive tests at crime scenes. LM is used to search for scattered blood traces or blood stains. LMG is used to detect fingerprints in latent blood stains and blood stains in laboratory settings. When only trace specimens are available, DNA extraction must be performed from LM- or LMG-treated specimens. No reports to date have been published on the actual effects of LMG on DNA extraction, although some reports suggest the potential influence of LM on DNA extraction. This study examined the effects of LM and LMG on DNA typing.
