Fig. 2From: The complex of miRNA2861 and cell-penetrating, dimeric α-helical peptide accelerates the osteogenesis of mesenchymal stem cellsA Gel retardation assay of complex of miRNA 2861 and ac-LK. The preformed miRNA/LK complexes were analyzed by electrophoresis on 1% agarose gel. B Size analysis of Complex A (50 nM of miRNA 2861 and 300 nM of ac-LK) and C zeta potential of miRNA 2861 and Complex A. particle size and charge were examined by DLS using a ZetasizerBack to article page
