contaminating DNA free Taq pol

[Zainul Zain]

Hi, I posted a question sometimes back regarding extraction of DNA from 
sputum specimens. Thanks for the great response. I finally got it to work.

But out of this I had also found that the Taq that we brought from Promega's 
didn't work well with DNA extraction from clinical specimens. Has anyone 
encounter the same problem???? 

I tried BRL and Perkim Elmer Taq and they 
work beautifully.
