Does carrier RNA interfere with the QuantiTect Whole Transcriptome amplification?
FAQ ID -3080

Small amounts of carrier RNA, such as used with RNeasy Micro Kit, do not interfere.  However, larger amounts such as used with QIAamp MinElute Virus Kits, the QIAamp Viral RNA Mini Kit, or the QIAsymphony DSP Virus/Pathogen Kits, will interfere with the Whole Transcriptome amplification.
