Design Notes

We have anther kind of NLS but only with one side. We chose two NLS for it may increase the probability of protein import into the cell nucleus. As 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 NLS, 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 two NLS 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 NLS and protein or any triple nucleotides. That depend on which will make the highest efficiency.

These two NLS sequence was from two sides in Cas9 sequence, plasmid px330, zhangfeng lab. For the too length and repeat A&G bases, we completely synthesis the sequence and add two BbsI site specially.
