From: Assessment of genomic imprinting of SLC38A4, NNAT, NAP1L5, and H19 in cattle
Analysis of genomic DNA and cDNA for SLC38A4 (A, B), NNAT (C, D), NAP1L5 (E, F), and H19 (G, H) genes using the primer extension method. A, C, E, and G, show two peaks in genomic DNA obtained from heterozygous individuals. B, primer extension analysis revealed two peaks (representing biallelic expression of SLC38A4) in cDNA products obtained from a wide range of tissues. D, F, and H, primer extension analysis shows monoallelic expression for NNAT, NAP1L5, and H19 respectively.
