Luminol is used by 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, in addition to the detection of specific proteins by Western Blot.
For analysis of an area, luminol can be sprayed evenly across the area, and trace amounts of an activating oxidant will cause the luminol to emit a blue glow that can be seen in a darkened room. The glow lasts for about 30 seconds, but the effect can be documented by a long-exposure photograph. It is important that the spraying be evenly applied to avoid creating a slanted, or biased impression, such as blood traces appearing to be more concentrated in areas which received more spray. The intensity of the glow does not indicate the original amount present, but only the distribution of trace amounts of substances left in the area.

I could have used this information over the last 29 years of my god damn life

My mom taught me to pack like this and she gets mad when I come to visit and sees that I don’t use it.

I need to remember this for uniforms.

Oh my god, I am learning this ASAP. HOW DID I NOT KNOW OF THIS BEFORE?!

HOW DID I NOT LEARN THIS BEFORE THE ARMY?!
