FAQ: DNA Damage ELISA Kit (8-OHdG)

Sample preparation

Q: Do I need to extract DNA if using urine, plasma, or serum?

A: It is not necessary to extract DNA if samples are a body fluid such as urine, plasma, serum, cerebrospinal fluid, or saliva.  Samples may need to be briefly spun down if there are insoluble particles in the sample, otherwise they can be used directly without any pretreatment.  For cell and tissue samples, DNA must be extracted first.
