Lac operator library

Parts K079045 through K079048 are libraries intended to introduce standardization and modularity for operator sequences. Each of the 4 collections has a different repressor specificity (Lac, Tet, Lambda and LexA) and consists of 3 different members with distinct binding affinities. Since operators flanked by Biobrick ends are unpractical and costly to obtain, both by dna sinthesys and phosphorylated oligos, we designed a "Standard Collection Vector". 320x240

This layout allows to get multiple small sequences with a single synthesis process and specifically enable the extraction of one or a combination of operators using exclusively Biobrick prefix and suffix restriction enzymes. Digestion and religation of the collection vector with Xba and Pst yields a single Operators 1 and Operator 3 vectors respectively (Es: Lac2 and Lac Symmetric) avoiding the troubles and optimization related to the run and purification of very small bands on agarose gel.

A similar approach using EcoRI give rise to a multiple Operator Vector comprising Operator 1 and Operator 2 sequences, usable per se as a composite regulatory site or further restrictable with PstI to extract the single Operator 2 (Es: Lac1)


The Libraries have been syntetized by Geneart in their standard pGA18 and pMA synthesis vector, with both ColE1 high copy number origin of replication and Ampicillin resistance.
