Why is there DNA in the no-template (negative) control when using the QuantiTect Whole Transcriptome Kit?

In no-template control reactions for the QuantiTect Whole Transcriptome Kit, primer–dimers can form. The highly processive Phi29 DNA polymerase used in the amplification step of the QuantiTect Whole Transcriptome procedure will extend these primer–dimers, leading to nonspecific amplification products.

These nonspecific products do not influence subsequent real-time PCR.
