Table 1. 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 Uppsala).

Sample	No. of molecules	Allele distribution for the LCT gene at Stockholm/Uppsala	Allele distribution for the LCT gene at Linköping

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.
