Lac Monomer B w/ 16 bp spacer for ICA

The part is flanked by UNS 2 and UNS 3 as per the WM UNS gibson cloning standard. This part is the LacO, 16BP spacer 'B' monomer for use in ICA to create repeated LacO Arrays of variable length. The monomer can be PCR amplified using UNS 4 and UNS 5 PCR landing pads. Next, the part should cut with BsmBI restriction enzyme to expose sticky ends and used to extend monomer in ICA. Monomer B (this part) can bind to Monomer A. This part contains the following: UNS 2 (WM standard gibson/amplification primer site) – UNS 4 (used to provide orthogonal amplification of monomers alone) – BsmBI site – sticky end 2 - Lac Repeat – 16 bp spacer (taken as first 16 bp from UNS X) – BsmBI site – Sticky end 3 - UNS 5 (orthogonal amplification in conjunction with UNS 4) – UNS 3 (WM standard gibson/amplification primer site).

ICA method and sequence design based on Briggs et al., 2012 and its supplement.

The UNS2, UNS3, UNS 4, and UNS 5 sequences are taken from Torella et al. 2013 and are ideal for cloning long sequences of monomers.
