Figure 3From: The sea lamprey Petromyzon marinusgenome reveals the early origin of several chemosensory receptor families in the vertebrate lineageChemosensory receptor expression in sea lamprey tissues. Lane 1: 100 bp DNA ladder; Lane 2: olfactory epithelium; Lane 3: adult sea lamprey testis; Lane 4: brain; Lane 5: liver; Lane 6: gill; Lane 7: kidney; Lane 8: parasite gonad; Lane 9: no template negative control. Reverse transcription PCR (RT-PCR) indicates that representative CR genes are expressed only in olfactory epithelium, testis and in parasite gonad (6425.OR330a, 16230.TAAR353).Back to article page
