Agilent 4200 bioanalyzer tapestation

Nucleic acid enrichment was performed with the complimentary primer (JS15) without a tetradecamer at the 3′-end in a 50 μL reaction mixture consisting of 10 μL cDNA, 5 μL of 10 μM JS15 primer, 25 μL of TaqMan environmental master mix (version 2.0) PCR buffer (Life Technologies, Grand Island, NY) and 10 μL of nuclease free water. After an initial denaturation step at 95 °C for 10 min, PCR was performed for 30 s at 95 °C, 45 s at 60 °C, and 45 s at 72 °C for 45 cycles followed by a final extension step at 72 °C for 10 min. The amplification products were purified with AMPure SPRIselect beads (Beckman Coulter, Indianapolis, IN), and a 1:0.8 ratio was selected to obtain an average DNA fragment size of 392 bp as confirmed by the Agilent 4200 Bioanalyzer TapeStation using the Agilent HS D1000 tape. DNA concentration was determined using the Qubit dsDNA HS kit with the Qubit 3.0 Fluorimeter (ThermoFisher Scientific, Waltham, MA).
