Imprinting Data For each cell up to a maximum of 4 samples were analysed, two undifferentiated Time points (Undiff T1 and Undiff T2) and two differentiated times points (Diff T1 and Diff T2). 11 imprinted loci were examined. For each loci there are two columns of data. DNA DNA indicates the sequence obtained at each loci. e.g. A/G: Alleles are heterozygous (A/G); A: Alleles are homozygous (A/A); G: Alleles are homozygous (G/G). RNA RNA indicates the sequence of the transcribes alleles e.g. A/G: Minor allele contributes 30-50% of total expression; A>G: Minor allele contributes 15-29% of total expression; A: Minor allele contributes 0-14% to total expression. n.s. - no sample; X - reaction failed.
