Figure 4: CpG-A and R837 induced TSG-6 expression in GEN2.2 cells. (a and b) Real-time PCR analysis and (c) ELISA analysis of GEN2.2 cells treated with CpG-A (2 μM) or R837 (10 ng/mL) shows induction of TSG-6 at both transcription and protein level. Graphs show data of at least 3 independent experiments performed in duplicate. Error bars indicate SEM. Paired Student's -test, , , and .
