From: Developmental expression of a functional TASK-1 2P domain K+ channel in embryonic chick heart
Expression of TASK-1 during chick heart development by RT-PCR. A: amino acid sequence alignment of pore regions of TASK-1 with all human TASK channels. B: TASK-1 and TASK-3 RT-PCR: Lane 0 shows 1 Kb DNA markers. Lane 1-6 as indicated at bottom (see text for definition). GAPDH expression was used as a reference and was equivalent in all samples after 25 to 40 cycle two step RT-PCR amplification. The size of cDNA products are indicated on the right hand and the developmental stages are labeled at the bottom.
