Depositor Comments

C-terminal 10x His tag is flanked by stop codons. Depending on the LP2 primer used in SLIC, this C-terminal tag can be fused to the target gene.

Use the one of the following linearization primers pairs for SLIC cloning. Choose one LP1 forward vector primer and one LP2 reverse vector primer:

LP1 forward vector primer:
SLIC Primer (3C site) 5' GGGCCCCTGGAACAGAACTTCCAG 3'

LP2 - select an LP2 primer below depending on which C-terminal tags you want to include fused to your gene of interest:
none SLIC Primer 5' CGCCATTAACCTGATGTTCTGGGG 3'
10His- SLIC Primer 5`GAGCATCATCATCATCACCAC 3'

Test each preparation of the plasmid by transforming it into non-resistant cells (ex. DH5a) to ensure negative selection by ccdB kills all the transformed cells as expected.
