Figure 1From: Different DNA methylation patterns detected by the Amplified Methylation Polymorphism Polymerase Chain Reaction (AMP PCR) technique among various cell types of bullsExamples of PCR markers generated by the AMP PCR technique. (a) Digestion-resistant (R) markers from primer No.21, (b) Digestion-sensitive (S) markers in sperm DNA produced from primer No.30 (white arrows indicate the PCR markers in the genomic samples and black arrows indicate the lost of the markers in the digested samples) and (c) Digestion-dependent (D) markers in fibroblastic DNA produced from primer No.1 (white arrows indicate no PCR markers in the genomic samples and black arrows indicate the PCR markers appear in the digested samples). G-S = Genomic sperm DNA, G-L = Genomic leukocytic DNA, G-F = Genomic fibroblastic DNA, D-S = Digested sperm DNA, D-L = Digested leukocytic DNA, D-F = Digested fibroblastic DNABack to article page
