How to store DNA from forensic samples eluted into water on the EZ1 biorobot in TE buffer instead?
For storage of DNA purified from forensic samples using the EZ1 DNA Tissue Kit in a buffered solution such as TE rather than water (used for elution in the EZ1 forensic protocols) we suggest the following:
Before storing the DNA, add 1/10 volume of 10x Forensic TE buffer (100 mM Tris·Cl, 1 mM EDTA, pH 8.3) to each sample. For example, add 5 µl of 10x Forensic TE buffer if you eluted in 50 µl. The DNA is ready to use, or can be stored at 2–8°C for 24 h, or at –20°C for longer periods.
