Hi Siti

in which tempreture you preserved your sample?

mostly the RNA is affected

Hi Fatma

-80C.

I actually want to extract DNA.

Hi Siti Radziah,

To extract DNA, You no need to isolate the buffy coat, you can store the blood samples as such at -80C.

if u wish to extract RNA you need to store in RNA later and 80C.

As u mentioned u need to extract DNA, So you no need to worry about it, you can go ahead with your DNA extraction.

ALL THE BEST

After I perform purification of Buffy coat using Maxwell, how long i can stored the purified DNA at -20C
