Effect of the choice of stable HKGs in the study of four samples of GSC. The relative fold expression (a) and the normalized fold expression of COLL1A1 of 4 samples of GSC. The normalization was performed with SDHA/B2M/ACTB, the most stable genes (b), GAPDH, the most usually used (c), and ALAS1/RPII, the least stable genes (d). Error bars expressed the standard deviation of the mean.
