Design Notes
For BbsI site, we have a series same design sequence. See the mechanism of BbsI site work below.
If you want to insert a coding sequence between promoter and polyA, the prefix of forward primer you design must contain GAAGACNNtaaaNNNN and reverse must contain GAAGACNNagttNNNN. The middle two Ns would be any bases for them will be cut off and the four Ns should be begins or ends of the coding sequence. You can get parts by above primers and digest by BbsI restriction enzyme. Then you can insert the parts into promoter and polyA seamless. The PCR product must be such sequence, including the protect bases, shows below.
And the reason why we designed that because we want to make a seamless gather between promoter and protein or any number nucleotides. That depend on which will make the highest efficiency.
Protocol
- Design the primers show below
TRE-3G promoter forward: T TCTAGA G TTTAAACTTTACTCCCTATC TRE-3G promoter reverse: ACGCA GGATCC AT GAAGAC GATTTACGAGGGTAGGAAGTG SV40 PolyA forward: ACGCG AGATCT AT GAAGAC CCAACTTGTTTATTGCAGCTTA SV40 PolyA reverse: AAAACTGCAG CGGCCGC T ACTAGT A TCCATGCCGAGAGTGATGAA
Sequencing Results
We sent fresh bacteria broth for sequencing using standard Biobricks sequencing primer VF2/VR. The sequencing cooperation we used is Invitrogen Guangzhou filiale.
Sequence of sequencing primer we used:
VF2: tgccacctgacgtctaagaa
VR: attaccgcctttgagtgagc
The result shows the same sequence with our ideal design.
Source
The plasmid was from our instructor, Huangwei's lab. And we design primers to copy down by PCR.
