3-Fragments direct ligation at one time??

[Xinkun Wang]

Hi, there,

I am trying to ligate my promoter and another encoding gene into a different 
vector. So there are 3 parts to be ligated here. I had thought to ligate my 
promoter into the vector first, then ligate my gene into the half-finished 
vector. But recently I am told I can ligate them together at one time. It 
saves time and work. So I am planning to try it. In my plan, I want to cut 
my vector with HindIII and BamHI, cut the promoter with HindIII and EcoRI, 
and the insertion gene with EcoRI and BamHI. After putting them together, I 
hope they can join each other to make the vector with my desired two inserts 
in the right orientation. Since I never did it before, I am still concerned 
about the effeciency of this approach. Does anybody use this method before? 
If it really works, that would be great. Any suggestions are welcome.

Thanks in advance.
