Hello ive made 2 threads about dna and spit within the last 2 weeks and i think ive learned a bit though there is more that i need to know

someone talked about brown ampules and having to seal them with heat though i am very uncertain of this and i was wondering if you guys knew any online guides or the like where they learn you how to do it? and is there anything i should keep in mind?

Hello i am interested in how long a spit swab lasts and how one could make it last longer than the 3 years ive found it could last
i am also interested in why the spit can not be used after longer time

this is purely for experiments please dont ask or say anything unrelated to the matter

also someone mentioned a man called dexter i wonder if anyone could tell me his last name? the friend from here spoke well of him and i really need any help i could get thank you
