Can the Certal CHO Positive Control DNA be used to create a qPCR standard for relative quantification?
FAQ ID -2979

For quantification, it is recommended that a gDNA standard from your production cell be prepared using, for example, the QIAamp DNA Mini Kit. The positive control provided with Certal Residual DNA Detection Kits is not suitable for use as a qPCR standard for relative quantification.
