Quantitative comparison of L-type calcium channel subunit expression in rat, monkey and human ON. A. Real-time quantitative PCR (rq-PCR) results for mRNA quantification of alpha 1A and alpha 1D. L-type calcium channels in rat, monkey and human ON. There is approximately 10-fold less (in monkey ON) and 5-fold less (in human ON) α1A and α1D calcium channel mRNA sequence than in the rat. B. Western analysis of human, monkey and rat ON homogenate, using antibody against the α1D subunit of the L-type calcium channel. The rat ON has a higher concentration of the α1D subunit of the L-type calcium channel, than do either primate species. Inset lower band: Actin loading.
