RNA was purified from rat tissue using the RNeasy Plus Universal Mini Kit, with or without gDNA Eliminator Solution. [A] Real-time RT-PCR analysis was carried out using RNA isolated from 25 mg frozen liver tissue. The CT value of all samples was comparable. DNA contamination was detected in the –RT control if gDNA Eliminator Solution was not used, whereas the samples isolated using gDNA Eliminator Solution showed minor or no DNA contamination. [B] RNA was purified from 25 mg stabilized heart tissues. Data obtained using the QIAxcel system demonstrates good RNA integrity regardless of whether RNA was isolated using gDNA Eliminator Solution.
RNA was isolated from the indicated amounts of RNAlater stabilized rat kidney using the RNeasy Plus Universal Mini Kit, or was precipitated using a precipitation reagent from Supplier AII. RNA eluates were analyzed by real-time RT-PCR, with and without reverse transcription, using the QuantiFast Probe RT-PCR Kit and the Rotor-Gene Q.
