Taq sticking to DNA

[GENE SIMON HUH]

Dear fellow netters,

     I missed the discussion a while ago regarding how proteinase K treatment 
of PCR products renders them more clonable.  Could someone please email me the 
reference?  In a related vein, does this reference mention whether Taq sticks 
tenaciously enough to the ends of DNA even through a standard agarose gel?  If 
so, which way does the gelshift occur, if any shift at all?

Thanking you all in advance,

Gene Huh
