When I was a student, we had to do Cesium Chloride preps of some
plasmid (do students still do that? I was terrified of the
ultracentrifuge, probably connected with my fear of washing machines:)
Of course the preps were HEAVILY laced with EB (not to mention CsCl!)
and of course I did JUST what the prof suggested NOT to do, which was
put my hand behind the tube while I punctured it with a large-bore
needle to pull the band with my plasmid. Whoops! So I had basically
injected (not deeply, fortunately) myself with EB/salt solution
glowing-red. I did survive, evidently, although the case for brain
damage could be made ;-)
