[Q]help-TA cloning after PCR

[601]

Hello, eveyone.
I want to know about how to do TA cloning well.  I have just made
a T vector by the following protocol.

pBluscript 10micrograms -(EcoRV digestion) - (Et-OH precipitation)- 
-(70degrees centigrade, 2hrs with dTTP in thrmocycler)-purification

But my vectors didn't work well.  The sample before ligation (no insert)
could make a lot of white colonies.  Maybe to add T residue to pBluscript
was not enough, I think.

Please give me som or ideas advice. Thank you in advance.
Thank you.
