European Man Found in Ancient Chinese Tomb, Study Reveals

European Man Found in Ancient Chinese Tomb, Study Reveals

Stefan Lovgren for National Geographic News

Human remains found in a 1,400-year-old Chinese tomb belonged to a man of European origin, DNA evidence shows.
Chinese scientists who analyzed the DNA of the remains say the man, named Yu Hong, belonged to one of the oldest genetic groups from western Eurasia.

The tomb, in Taiyuan in central China, marks the easternmost spot where the ancient European lineage has been found (see China map).

"The [genetic group] to which Yu Hong belongs is the first west Eurasian special lineage that has been found in the central part of ancient China," said Zhou Hui, head of the DNA laboratory of the College of Life Science at Jilin University in Changchun, China.

DNA Library Construction

DNA Library Construction


In biological engineering and combinatorial chemistry, it shows great promise indiscovering and creating novel materials which perform as artificial receptors or catalysts.
A property of the library is most important and progress had been made inconstructing biological library of peptide1,polysome2, phage3 and nucleic acid. Here are some
protocols that will be useful to your research work.


1. Genomic library, cDNA library, YAC library, and screening of library.
2. Standard microquantity cDNA libraries.
3. cDNA library screening protocol
4. cDNA library construction protocol.
5. Microsatellite library.
6. Microsaellite library protocol
7. Random shotgun library construction.
8. Methods for use with mTn-3xA/GFP mutagenized library.
9. Genomic library construction.
10.Plasmid library amplification.
