Figure 5From: Investigation of factors responsible for cell line cytoplasmic expression differencesCytosolic nuclease assays of BHK and COS-7 cytoplasmic extracts. 200 ng/μg plasmid DNA was incubated and aliquots were taken at time points indicated. No significant difference in nuclease activity between the BHK and COS-7 cytoplasmic extracts was observed.Back to article page
