Droplet digital PCR is a method for accurately quantitating copies of DNA or RNA in a sample. Enzymes are incubated overnight with Lambda DNA to confirm that there is no additional non-specific nuclease activity present. Isothermal amplification generates many copies of a target sequence in a short period of time, at a constant temperature. Enzymes are screened by qPCR to ensure no contaminating genomic DNA is present. restriction enzymes with altered specificities and improved performance. To ensure that there are no contaminating enzymes that could cause nickng or non-specific nuclease degradation, reagents are incubated with supercoiled plasmid DNA for 4 hours to demonstrate the absence of endonuclease contamination. Working continuously to be worthy of that distinction, NEB strives to develop enzymes of the highest purity and unparalleled quality. A restriction enzyme, restriction endonuclease, or restrictase is an enzyme that cleaves DNA into fragments at or near specific recognition sites within molecules known as restriction sites.
