Figure 3. Semi-quantitative RT-PCR for leptin receptor mRNA.
Primary fetal rat lung fibroblasts (FrLf) and type II cells, WI38 human embryonic lung fibroblasts and H441 adult lung epithelial cells were assayed for leptin receptor mRNA expression. Co-amplification with GAPDH cDNA was used as an internal standard for the normalization of the aliquot volumes for leptin receptor mRNA expression.
