Free DNA from culture media

Postby ricardopella » Jul 20 2017 11:09 am

How can I safely eliminate cell-free DNA from my culture media? Can I use DNAase without damaging my cells in culture?

Free DNA in culture media comes from fetal calf serum. Can your cell grow in serum-free medium?

DNase should not damage cells. But it will be difficult to determine how much DNase you need to clear the free DNA in the medium.
