Depositor Comments

This plasmid is an empty vector to be used with a LIC cloning protocol.

To clone into this vector, add LIC version 2 fusion tags to the 5' end of your PCR primers.
Forward - 5'TTTAAGAAGGAGATATAGATC3'
Reverse - 5'TTATGGAGTTGGGATCTTATTA3'
In addition, ensure that your open reading frame contains an ATG start codon.

Linearize the plasmid with EcoRV and gel purify.

When digesting the DNA with T4 polymerase for LIC version 2, use dGTP for insert and dCTP for vector. Series 371 vectors have BioBrick restriction sites to facilitate subcloning reactions to make polycistronic expression vectors. NotI, PacI, AsiSI, and SbfI are the restriction enzyme sites that flank your open reading frame. More information on this vector can be found through http://qb3.berkeley.edu/qb3/macrolab/.

In the 371-Series plasmids, upstream of each ribosome binding site is a Csy4 target sequence that allows the polycistronic mRNA to be cleaved upstream of each message when your plasmid is co-expressed with the Csy4 protein. By cleaving the message we hope to avoid detrimental mRNA structures that may result from having a long polycistronic message.
