The effects of EDTA and contaminating metals on Fe, Cu and Zn in deoxyribonucleoprotein

1. 1. A substantial loss of native metals in DNP was observed when EDTA was present during cell homogenization or in the final extract. 2. 2. Similarly, the presence of trace amounts of Fe. Cu, and Zn resulted in metal contamination.
