Table 3.
Candidate reference genes ranking according to geNorm.
| Rank | Gene Symbol | M value | V value |
| 1/2 | SDHA/HPRT | 0.232 | --- |
| 3 | R18S | 0.274 | 0.090 |
| 4 | B2M | 0.311 | 0.078 |
| 5 | UBB | 0.335 | 0.064 |
| 6 | ACTB | 0.376 | 0.068 |
| 7 | RPL32 | 0.405 | 0.059 |
| 8 | TFRC | 0.448 | 0.065 |
| 9 | GAPDH | 0.521 | 0.080 |
M value is calculated as average expression stability of control genes during stepwise exclusion of the least stable controls. V value is calculated as the pair-wise variation between two sequential normalization.
