I have tried using this approach to clone PCR products and so far have had
no luck. I get a significant background of blues, suggesting that the T
addition isn't very efficient (at least for me) and around 10% whites (even
on no insert control ligations) and all whites that I've looked at so far
have been empty ! Can anyone give me an idea of the background usually
experienced when you clone in this way. If anyone out there buys the
commercial T-vector kits and does a no insert control ligation, do you get a
high background of white colonies ?
Any suggestions (at all) most welcome
