This high-throughput method measures residual CHO host cell DNA with our proprietary extraction procedure, which does not use iodine or glycogen. Cell line-specific CHO DNA calibrators are included, and upon completion of the extraction, the samples are reacted with PicoGreen® solution. Time to completion is under 2 hours for multiple samples and multiple deep-well plates. Each kits upplies enough reagents for the analysis of 96 samples.
