(a) Real-time RT-PCR (SERPINB2) guided purification of a gene regulatory compound from TSS. (b) LC/MS positive ion profile of the purified active compound. (c) SerpinB2 Real-time PCR assay of the active compound (5 μg/ml). GAPDH was used as the endogenous control. Log2(RQ) corresponds to the Log Ratio value in the expression profile (Table 1). RQ stands for relative quantitation (i.e., the fold-change ratio) in real-time PCR analysis.
