In order for the precise measurement of PERV gene copy number, it is definitely important to draw the accurate standard curve. In so doing, a high-quality plasmid DNA for each PERV genes is required.

Mr. Toan (NIAS-V) is taught how to go through the procedure by Drs Taniguchi & Arakawa (NILGS) during 26-27 Feb 2018.


Dr. Taniguchi point out a good colony of the competent cells identified to have the plasmid which is aimed to be used.
