Isolating whole genomic DNA

  1. This is my first time isolating the whole genomic DNA from cells. I have two cell line HeLa and Human fibroblasts (almost fully confluent T-25 flasks). The problem is that the protocol which is to be followed for genomic dna extraction is only suitable for DNA solutions less than or equal to 1mg/ml (according to the instructions). How do I determine the weight of DNA that I have beforehand? I'm confused on that point. (Note I can't count cells either).
