During excavations on Lolland, archaeologists have found a … According to the researchers, it is a new untapped source of ancient DNA. – and extracts the DNA from them to create a 3D face model. Danish scientists extract human DNA from Stone Age ‘chewing gum’ Scientists in Denmark have found DNA from a piece of birch pitch from a person who lived more than 5,700 years ago. During excavations at Syltholm, in southern Denmark, archaeologists found the chewing gum consisting of birch resin. For more information view the SAGE Journals Article Sharing page. On average, the QIAamp kit also … After seeing this, you may think twice before spitting out a piece of gum or dropping a cigarette butt. NIH In this study, several popular extraction methods were tested, including Chelex-100, phenol-chloroform-isoamyl alcohol (PCIA), DNA IQ, PrepFiler, and QIAamp Investigator, and the quantity of DNA recovered from chewing gum was determined using real-time … The purpose of this study was to evaluate which DNA extraction method yields the highest quantity of DNA from chewing gum. PLoS One. eCollection 2020. DNA from Stone Age ‘chewing gum’ tells an incredible story For the first time, scientists used 5,700-year-old saliva to sequence the complete human genome of an ancient hunter gatherer, as well as the world of microbes that lived inside her.

In this study, several popular extraction methods were tested, including Chelex-100, phenol-chloroform-isoamyl alcohol (PCIA), DNA IQ, PrepFiler, and QIAamp Investigator, and the quantity of DNA recovered from chewing gum was determined using real-time polymerase chain reaction with Quantifiler. Oh, and she likes gum. The QIAamp performed best when DNA was extracted from whole pieces of control gum (142.7 ng on average), and the DNA IQ method performed best on the environmental whole gum samples (29.0 ng on average).

Scientists have been able to extract the entire genetic code of an ancient human using a piece of "chewing gum" dating back 5,700 years. As expected, results indicate that all methods tested yielded sufficient amplifiable human DNA from chewing gum using the wet-swab method. Moore D. Purification and concentration of DNA from aqueous solutions.

Some society journals require you to create a personal profile, then activate your society account, You are adding the following journals to your email alerts, Did you struggle to get access to this article? However, this method should be avoided with whole gum samples (no DNA yield) due to the action of the organic reagents in dissolving and softening the gum and inhibiting DNA recovery during the extraction. Danish scientists extract human DNA from Stone Age ‘chewing gum’ Scientists in Denmark have found DNA from a piece of birch pitch from a person who lived more than 5,700 years ago.

With guidance, it has been possible to recreate what the girl who chewed on the resin looked like.  |  Researchers from the University of Copenhagen have succeeded in extracting a complete human genome from a thousands-of-years old “chewing gum”. The purpose of this study was to evaluate which DNA extraction method yields the highest quantity of DNA from chewing gum.  |  According to the researchers, it is a new untapped source of ancient DNA. doi: 10.1371/journal.pone.0116351. eCollection 2014.
