Depositor Comments

This plasmid is an empty vector. Your gene can be inserted with a LIC cloning protocol. All 2-series vectors work as single-expression vectors, as well as transfer vectors for our polycistronic system.

2K-T has a TEV-cleavable N-terminal His6 and MBP fusion tag to enhance solubility and ease purification. These tags are preceded by a periplasmic locator signal, which is autocleaved during secretion. The PPL tag may be helpful if your protein binds to or interferes with intracellular E. coli molecules, since your protein of interest is safely sequestered in the periplasm. It may also be helpful if your protein of interest is more stable in the periplasmic environment. Protein purification may also be made simpler using this expression method.

The LIC cloning site is flanked by 5 pairs of restriction sites, so that your gene can easily be subcloned into our polycistronic destination vectors (2D, 2E, or 2Z).

To clone into this vector, add LIC v1 tags to the 5' end of your PCR primers.

Forward - 5'TACTTCCAATCCAATGCA3'

Reverse - 5'TTATCCACTTCCAATGTTATTA3'

Linearize the plasmid with SspI and gel purify.

When digesting the DNA with T4 polymerase, use dCTP for insert and dGTP for vector.
