pGA1A3, Gibson assembly plasmid (bglBrick) with pLac-GFP insert

This is a Gibson Cloning friendly 1A3 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 1A3 vector.

Usage and Biology

This is a high copy plasmid backbone that confers ampicillin resistance. It was deposited in the registry with an insert coding for LacI-repressible GFP. This plasmid has been altered to conform to [http://dspace.mit.edu/handle/1721.1/46747 RFC 21] standards, with arbitrary, Gibson-friendly sequences placed in between the restriction enzyme sites EcoRI-BglII, and BamHI-PstI.

Characterization

This plasmid 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.
