But what if you target immoral people? You might even prevent future homicides if you murder murderers. It's like a social good, no?

>> No.11400297

>>11399635
its not for me to decide whats immoral or not as if i were to decide to kill immoral people i would be quite immoral my self but this does not pertain to the matter at hand and i prefer not to discuss killing as i am uncomfortable with the subject and i am only here asking about spit

>> No.11400305

>>11399595
i have considered this but i am unsure of the quality of the spit considering i wouldnt be able to maintain optimal temperatures the fear of power outages and just the general negative effects of frost on the dna

>its not for me to decide what's immoral
So you just float through life without any moral/ethical compass? Surely you judge people all the time dude
>if i were to decide to kill immoral people i would be quite immoral my self
Are you saying soldiers are immoral? Is killing in self-defence immoral? What are you, some kind of amoral monastic pacific or something?
>i prefer not to discuss killing as i am uncomfortable with the subject
Bruh...It's all good. It's just vigilantism. Like Batman, but more conclusive.

i only judge superficially i can not make judgements about their characters without being too judgy its about control and i lack control in with my judgement so i just out right dont judge
>Are you saying soldiers are immoral? Is killing in self-defence immoral? What are you, some kind of amoral monastic pacific or something?
i dont think soldiers are immoral their purely following orders and i seen them mostly as neccesary robots i dont know what a monastic pacific is sorry
>Bruh...It's all good. It's just vigilantism. Like Batman, but more conclusive.
batman is a dumb super hero lacking any sort of character and is just a dude with parental issues and money

The DNA in the sampe decays due to oxidation reactions, exposure to UV-light which will break up chemical bonds and/or is literally eaten up by microbes and fungus.

To store it you need to seal the sample in a brown glass ampule (which minimizes decay due to light) in an organic solvent like Ethanol or Formaldehyde (which kills spores and microbes) Before sealing, the ampule must be evacuated (no oxygen present). Store at a cool and dark place and your sample should last forever.

so if i were to vacum pack the swab and keep it in a dark cool place it would last forever?

>> No.11401774

>>11401746
No. Your 'vacum pack' is neither sterile, nor UV-resistent.

a brown glass ampoule is 10 cents on ebay. Blowtorch and rubbing alcohol at your local hardware store/pharmacy. Just leave out the evacuation step. No guarantees though

Are you retarded? An ampoule is sealed by melting the glass. rubbing alcohol is the (cheapest) solvent you can put your sample in.

But honestly, maybe you should just abandon the project. You'd manage to kill yourself in the end.

not retarded just not learned in the matter thats why i am here asking these questions maybe you should take a break off the internet for a bit?
