We can go back to the house at spray Luminol.
Even after 165 years, it glow blue.
We use this product when we need to find DNA.
Under carpets, floor board and cracks in baseboard trim.
Luminol is used by JBI forensic investigators to detect trace amounts of blood left at crime scenes, as it reacts with iron found in hemoglobin.
It is used by biologists in cellular assays for the detection of copper, iron, and cyanides, as well as of specific proteins by western blot.
The killer may have cut him self. Case information.
We can spray Luminol evenly across the basement area, and trace amounts of an activating oxidant will cause the luminol to emit a blue glow that can be seen in a darkened wine cellar room. The glow lasts for about 30 seconds, but the effect can be documented by a long-exposure photograph.
It is important that we are spraying evenly to avoid a biased impression, such as blood traces appearing to be more concentrated in areas that received more spray.
The intensity of the glow does not indicate the original amount present but indicates only the distribution of trace amounts of substances left in the area.
Our lab has so many ways to solved a cold case.
