Figure 1.

Detection of the two ORP1 mRNA variants encoding ORP1L and ORP1S. The numbered boxes in the middle denote exons of the ORP1 gene. The bars consisting of black and gray boxes represent the two mRNAs; black indicates translated and gray nontranslated regions. The positions of primers for specific detection of the respective mRNAs are shown with arrows. The primer pairs are indicated within parentheses. The sequences of the primers are listed in Table 2.
