pGA3K3, Gibson assembly plasmid (bglBrick) with pLac-GFP insert

This is a Gibson Cloning friendly 3K3 plasmid backbone that was made by [http://2011.igem.org/Team:Washington UW iGEM Team 2011] as part of the [http://2011.igem.org/Team:Washington/Magnetosomes/GibsonVectors Gibson Assembly toolkit]. Using this plasmid increases the efficiency for anyone doing Gibson cloning into a 3K3 vector.

Usage and Biology

This is a medium copy plasmid backbone that confers kanamycin resistance. It was deposited in the registry with an insert coding for LacI-repressible GFP.

Below is the gel image of the plasmid amplified with universal pGA backbone primers pGAsuffix_fwd and pGAprefix_rev. The band is near the expected length of 2750 bp.

Characterization

A sister plasmid (pGA1A3) with the same BglBrick prefix and suffix regions has been shown to have much higher efficiency than the equivalent pSB vector. We determined the cloning efficiency by dividing the # of bright colonies by the (# of total colonies - # of background colonies). The background colonies were determined by a control sample containing 100 picograms of just the pGA backbone. See [http://2011.igem.org/Team:Washington/Magnetosomes/GibsonResults#Comparison_between_pGA_and_pSB_vectors Gibson Assembly efficiency assay] page for details on the protocol and efficiency measurements.
