Figure 2From: Evolutionary history of the alpha2,8-sialyltransferase (ST8Sia) gene family: Tandem duplications in early deuterostomes explain most of the diversity found in the vertebrate ST8Sia genesExpression pattern of the zebrafish ST8Sia genes in various tissues, as determined by RT-PCR. Lane 1, 36 h embryo; lane 2, ovary; lane 3, intestine; lane 4, brain. The zebrafish β-actin gene was used as a positive control of PCR amplification.Back to article page
