(A) Combine Accell siRNA with Accell delivery media (or other low- or no-serum media). (B) Add Accell delivery mix directly to cells and incubate for 72 hours.
Neonatal rat ventricular myocytes were incubated with 1 μM Accell Green (A; Cat# D-001950-01) or Red (B; Cat# D-001960-01) Non-targeting siRNA for 72 hours in Accell delivery media (Cat# B-005000). Nuclei were stained with DAPI (blue). Labeled control uptake showed diffuse cytoplasmic localization in nearly all cells. The bar graph indicates the level of gene silencing achieved with Accell GAPD Control siRNA (Cat# D-001930-03) and Accell GAPD Control Pool (Cat# D-001930-30) control reagents when used with neonatal rat ventricular myocyte (NRVM) media or Accell delivery media. Myocytes were prepared as described in Maass AH & Buvoli M. Cardiomyocyte preparation, culture, and gene transfer. Methods in Molecular Biology 2007;366: 321-30. mRNA expression was determined by QuantiGene branched DNA assay (Panomics).
Internal validation and peer-reviewed publications report numerous successes with difficult-to-transfect cell types. See the References tab for a list of publications.
