TA cloning: thanks!

[Denni Schnapp]

Thank you for all the advise on TA cloning. To summarize: apparently, the
Promega PGem kit is fine, but there might be some variation between kit
performance. Invitrogen Topo 2.1 kit is very good (but costly, I think).
It is best to chloroform-extract the PCR reaction at once to inactivate
Taq, but inactivation may be incomplete. A valuabe piece of advise was to
add more Taq to the product after storage and incubate at 70-72 deg. C for
10 min prior to cloning - I'm off to try that next!

Thanks again.
