For my master thesis project I received four gun shell casings. The goal is, to recover as much of the #geneticmaterial
as possible using #swabs
To do so, I stain the touched casings with #diamondnucleicaciddye
and visualize using a #dinolite
All those green spots you see is stained #genetic
material, still packaged in the shed #cells
This way, I can see that DNA was deposited, and later check, if I successfully removed some off of the surface.
In the picture, one of my volunteers touched a 6.5x55 SE cartridge and left quite some traces behind... :)
