qPCR revealing ubiquitous B4GAT1 and LARGE expression in all tissues analyzed, with highest expression of LARGE in brain and heart. cDNA was synthesized using random primers and oligo(dT) on commercially available human tissues RNAs. For each tissue, B4GAT1 and LARGE were specifically amplified, in triplicate, in the presence of SYBRgreen, and their expressions was normalized to that of the 28S RNA (normalization control). The expression in each tissue is referenced with respect to that in brain. Analyzed tissues: Br (brain), Ey (eye), He (heart), Ki (kidney), Li (liver), Lu (lung), Pa (pancreas), MG (mammary gland), Ov (ovary), Pl (placenta), Pr (prostate), SM (skeletal muscle), Sp (spleen), Te (testis), Th (thymus). Error bars represent.
