Amount of an 80bp mitochondrial fragment (number of templates per real-time PCR reaction, with 5 µl DNA extracts used in 25 µl reactions, average from two real-time amplifications), and allele status in seven samples of ancient human remains typed in three laboratories (Linköping, Stockholm, and Up

The allele status in the Linköping samples was based on between 3 and 7 amplifications deriving from two independent extractions, while 3 amplifications deriving from one extraction in each case were made in Stockholm and one in Uppsala.林雪平（Linköping）样本的等位基因（allele）状态，依托于两次独立提取所得到的3至7次扩增产物；而来自每个样本单次提取的3次扩增反应在斯德哥尔摩（Stockholm）开展，另有1次扩增反应在乌普萨拉（Uppsala）进行。
