[Histonet] Does EDTA destroy DNA during decalcifying process?

[Martina Sladkova]

Hello !
 
Does anyone know whether EDTA destroys DNA during decalcifying process and whether  it would be better to fix the sample before adding EDTA? 
My samples are natural coral cubes of 3mm. It is carbonate calcium. The coral cubes are seeded with mesenchymal stem cells. I need to extract DNA in order to evaluate cell  proliferation. 
 
Thank you very much in advance,
