Figure 2From: Lipopolysaccharide-induced expression of surfactant proteins A1 and A2 in human renal tubular epithelial cellsRT-PCR analysis of the surfactant protein A (SP-A) gene in human tissues. SP-A and GADPH transcripts were amplified by RT-PCR with gene-specific primer pairs. The products were analysed by 2% agarose gel electrophoresis. Human renal tissues (Lane 2) and HK-2 cells (Lane 3) showed a clear band of SP-A cDNA. PCR amplification products of the lungs were used as positive controls (Lane 1). GAPDH control product was also used (200 bp).Back to article page
