What is elution Buffer ATE of the QIAsymphony DNA Investigator Kit?
Buffer ATE of the QIAsymphony DNA Investigator Kit is a low-EDTA elution buffer optimized for long-term storage of DNA as well as performance in sensitive downstream applications. Alternatively, casework protocols using water for elution are available.
Buffer ATE contains a small amount of the preservative sodium azide. If the eluate is measured for absorbance the spectrophotometer should be blanked with the buffer ATE as sodium azide absorbs strongly at 230 nm.
