BLUNT CLONING With EcoNI - (May/04/2011 )

Hi Guys,

Just hoping anyone has advice on improving a blunt end clone?

The vector is linearized with EcoNI and the fragment i am inserting has been digested out with bgl II on both sides of the fragment.

I have repeated the process multiple times, though in general this is the order.

1) Digest Vector and Fragment
2) Gel Purify/Extract.
3) T4 or T1 Polymerase Treatment
4) Dephosphorylation with Antarctic Phosphatase for Vector Only.
5) Purify
6) Ligate with Promega T4 DNA Ligase at 16*C ON.


Thank you in advance

EcoNI digests CCTNN^NNNAGG
in my case the N's are CT^CAC. This leaves a 1 bp 5' over hang of 'C'. I would like to ligase with a bgl II site which is AGATCT. I've considered designing a bgl II linker for my vector, however i am also uncertain if a linker will anneal to the single bp from EcoNI?
