Figure 1From: Expression of the α7 nicotinic acetylcholine receptor in human lung cellsAgarose gel showing α7 nicotinic acetylcholine receptor expression in SCLC cell lines. cDNA was amplified by PCR using the human α7 primers. SCLC cell lines: 1) WBA; 2) NCI-H69; 3) NCI-H82; 4) NCI-H146; 5) NCI-H187; 6) NCI-H209; 7) NCI-H526. For all gene expression experiments, negative control reactions were performed and found to be negative. The bands were consistent with the expected size, 335 bp. M-100 bp DNA ladder.Back to article page
