Default DNA extraction 230/280



Hi,

I have tried to extract DNA from paraffin-embedded specimens using the Qiagen kit and protocol. The concentration of DNA and 260/280 is at a good level but the 230/280 is too low. I have tried repeating the salt/phenol wash and also tried the Qiagen DNA clean up kit. Any suggestions? Thanks!
