Preparation of Plasmid DNA for TASQ This information is for Clients who will be sending plasmid DNA to TASQ for final purification. 1) Client must first prepare 30-50ug of DNA. The use of a kit which results in endotoxin-free, clean plasmid is recommended. 2) Restriction enzyme digest is done to liberate the DNA fragment from the DNA backbone. A final yield of 10-20ug is recommended. Inactivate the digest. 3) Once the digestion is completed, a small sample of the digest must be run on a gel to ensure that the digest is complete. Take a gel picture of the digest. This must be sent with the DNA to TASQ. 4) DNA can be sent via Australia Postpak overnight.
