A specific decided expression vectorThe GeneArt Synechococcus Protein Expression Vector is designed to provide constitutive expression in Synechococcus elongatus. Expression is controlled by promoter psbA1, a ribosome binding site (RBS), and optional initiation and stop codons depending on gene location. The vector provides purification and detection tags at the N- and C-termini: an N-terminal polyhistidine tag with a TEV recognition site for optional cleavage and a C-terminal V5 epitope followed by a polyhistidine tag. Two MCS sites provide the flexibility to attach either, both, or no tags toyour protein. Our pSyn_6 vector is also compatible with seamless cloning, an optional cloning method that results in no extra sequences in your final construct.Features of the vector include:• Strong constitutive promoter, psbA1, for robust expression of recombinant gene of interest• Ribosome binding site (RBS) for improved expression of some genes• Targeted integration of your gene of interest into the Synechococcus elongatus genome• N-terminal 6His-TEV and C-terminal V5-6His epitope tags• Spectinomycin-resistance gene for selection in Synechococcus• Flexible, multiple cloning site vector>80% integration efficiencyThe transformation of Synechococcus elongatus PCC7942 relies on homologous recombination between the cell’s chromosome and exogenous DNA that is not autonomously replicating and contains sequences homologous to the chromosome. The location of integration into the chromosome (neutral site, NS1) was developed as a cloning locus, since it can be disrupted without any aberrant phenotype, thus allowing recombination of ectopic sequences. When transformed with vectors containing an antibiotic resistance cassette and neutral site sequences, a double homologous recombination event occurs between the neutral site vector and the Synechococcus elongatus chromosome. The selective marker (spectinomycin) and the gene of interest driven by a promoter are inserted into the neutral site and the vector backbone (pUC) is lost, allowing the expression of recombinant genes in Synechococcus elongatus PCC 7942.Gibco BG-11 Media—optimized for cyanobacteriaGibco BG-11 Media, available separately, is optimized for the growth and maintenance of select Cyanobacteria including Synechococcus elongatus. The 1X formulation lets you avoid laborious media preparation steps. Award-winning bottle design is easier to use in the biosafety cabinet, minimizes the risk of contamination, and helps you perform cell culture more consistently. Superior packaging and quality, greater reliability, and improved consistency in Cyanobacteria culture results in better overall efficiency and more robust data.
