Figure 5

qRT-PCR validation of in silico expression profiles. (a) Clone MRA-1648 showed a four-fold higher expression in retina than in brain or lung. Its expression in other tissues is at least eight-fold less than in the retina. One negative control curve is shown to demonstrate that samples are free of genomic contamination. The inset figure shows the qRT-PCR curves of Hprt, all of which cross the baseline at 24 ± 0.5 cycles, indicating equal input of cDNA in different tissue samples. (b) The relative expression units of three clones, MRA-0545, MRA-1648 and M15E-2659, in E15.5 eyes (blue), PN2 eyes (purple) and adult retina (yellow) were calculated by their cycle differences from Hprt during qRT-PCR experiments. Hprt was arbitrarily assigned a value of 10,000. The high transcript level of MRA-0545 and MRA-1648 and low level of M15E-2659 in adult retina confirmed the in silico profiles shown in Table 5.
