Figure 1From: Role of relaxin-2 in human primary osteosarcomaDetection of relaxin-2 mRNA expression in tissue samples. A. Gel images of electrophoresis. B. Real-time quantitative RT-PCR assay. Osteosarcoma tissues showed obviously higher relaxin-2 mRNA expression than corresponding non-tumor tissues. β-actin was used to normalize for any differences in mRNA between lanes. Student’s t-test showed a significant difference (*P < 0.01).Back to article page
