Fig. 5From: Recognizing and stabilizing miR-21 by chiral ruthenium(II) complexesDownregulation of miR-21 after treatment with different concentration complexes in cell level tested by quantitative PCR (RT-qPCR). The amplification plot and dissociation curve of RT-qPCR of miR-21 transcript expression profiles of both isomers at various confluences are shown in Additional file 1: Figure S6Back to article page
