High fractions of exogenous DNA in human buccal samples reduce the quality of large-scale genotyping.

Analytical biochemistry - 15 Dec 2008

Herráez David López, Stoneking Mark

Abstract excerpt

Buccal cell samples are considered a reliable source of DNA for genotyping studies. However, a potential drawback is the presence of exogenous DNA that is coextracted with human genomic DNA. A set of saliva and cheek swab samples, in which the fraction of human DNA varies from 10 to 96%, was geno...
