烟蒂样本采集方法


很多人都知道吸烟有害健康,但是想戒掉却怎么样都戒不掉,只能继续抽下去,一抽就是几十年,因为这样科学家从中发现了一个秘密,烟头掺杂了我们人类的DNA,可用做亲子鉴定?


烟蒂采样方法:

人体内所有器官组织都可以作为DNA检测样本,包括,血液,血痕,带毛囊的头发,口腔拭子(口腔粘膜)等,特殊样本包括,精斑,羊水,肌肉组织,牙齿,都可以采集用于DNA检测;


烟蒂采集注意

1、烟头不能是干净的,需要采集5根以上,需要带上吸烟者一些口水的;

2、收集烟头的时候,应该注意清洁双手,以免破坏DNA,不要直接碰触烟头烟蒂部位,可用夹子;

3、用干净的纸巾,分开包好;


亲子鉴定采样方法有很多,但是基本鉴定原理是一样的根据孟德尔遗传学定律,运用现代科技去提取样本DNA采集其中片段,通过对比之间的多个位点,来确认亲缘关系,得出结论。


烟蒂样本可邮寄快递,尽快送达检测中心为佳。




Sampling method of cigarette butts


Many people know that smoking is harmful to people's health, but if they want to quit, they can't stop smoking. They can only continue smoking for decades. Because in this way, scientists have discovered a secret: cigarette butts are adulterated with human DNA, which can be used for paternity testing?


Cigarette butts sampling method:


All organs and tissues in the human body can be used as DNA test samples, including blood, blood stains, hair with hair follicles, oral swabs (oral mucosa), etc. special samples including seminal plaque, amniotic fluid, muscle tissue and teeth can be collected for DNA detection;


Tips for cigarette butts collection:


1. Cigarette butts can not be clean, need to collect more than 5, need to take some saliva of smokers;


2. When collecting cigarette butts, you should pay attention to clean your hands to avoid DNA damage. Do not directly touch the cigarette butts, but use clips;


3. Use a clean paper towel and wrap it separately;


There are many sampling methods for paternity testing, but the basic identification principle is the same. According to Mendel's law of genetics, modern technology is used to extract sample DNA, collect fragments, and compare multiple loci between them to confirm the genetic relationship and draw a conclusion.


Cigarette butts samples can be sent to the testing center by post and express delivery as soon as possible.
