Figure 3From: 5-HT receptors mediate lineage-dependent effects of serotonin on adult neurogenesis in Procambarus clarkii5-HT receptor mRNAs are expressed in the brain of the crayfish P. clarkii. RT-PCR was performed on total RNA sampled from P. clarkii brains. The expected PCR products based on GenBank P. clarkii sequences are 515 bp for 5-HT1α mRNA (lane 2), 546 bp for 5-HT2β (lane 3) and 427 bp for 18S rRNA (lane 4). Lane 1, 1-kb DNA ladder.Back to article page
