The GeneArt® Synechococcus TOPO® Engineering Kit is the first commercially available genetic modification and expression system for the prokaryotic cyanobacteria, Synechococcus elongatus. The GeneArt® Synechococcus TOPO® Engineering Kit with media combines TOPO® cloning technology, optimized cloning and expression vectors, frozen cells, simple protocols, and Gibco® BG-11 Media to create the first standardized, complete system for algae research and metabolic engineering in this important model organism. Exceptional purity and Invitrogen’s premier TOPO® cloning technology help ensure reliable results and fast ramp to bioproduction scale.
• Create transformed algal cells typically in just 7-10 days
• Standardize experiments with genetically consistent frozen cells
• Save time required for strain optimization and transition to bioproduction
• Rest easy with excellent strain viability and purity
• Avoid laborious media preparation steps

Versatile Cyanobacteria for Study or Bioproduction
The cyanobacterium Synechococcus elongatus strain PCC 7942, is an excellent system for studying photosynthesis, circadian rhythms, nutrient regulation, environmental response, and lipid metabolism. Cyanobacteria, also known as blue-green algae, are a common platform for bioproduction of alcohols and chemicals due to their small genome size and the ease with which it can be genetically manipulated by natural transformation.

Shorten the Time from Cloning to Expression
Cells are ready for transformation typically in less than 5 days with straightforward, robust resuscitation and growth protocols. GeneArt® Synechococcus pSyn_1/D-TOPO® Vector facilitates rapid, directional TOPO® cloning of blunt-end PCR products for regulated expression in Synechococcus elongatus. Parallel growth and cloning workflows allow you to obtain transformants typically in just 7-10 days (Fig. 1).

Reliable and Consistent Cell and Vector Performance
Until now, researchers often relied on colleagues and culture collections to obtain cells, vectors, cloning tools, and protocols for working with Synechococcus elongatus. Cells from these sources often ship on agar slants which could become contaminated and have low survival rates. Additionally, vectors passed down from uncontrolled sources could contain undocumented changes, leading to further wasted time. The GeneArt® Synechococcus TOPO® Engineering Kit provides peace of mind with exceptional purity, viability, and cell lot-to-lot consistency. No more genetic drift from ongoing transfer cultures and cloning failures from undocumented sequence changes.

Gibco® BG-11 Media – Optimized for Cyanobacteria
Gibco® BG-11 Media, included with this kit, 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.

Synechococcus elongatus TOPO® Cloning Vector
pSyn_1/D-TOPO® Vector is designed to facilitate rapid, directional TOPO® cloning of blunt-end PCR products for regulated expression in Synechococcus elongatus. Features of the vector include:
• Directional TOPO® cloning site for rapid and efficient directional cloning of a blunt-end PCR product
• Basal expression of your gene of interest via the weak constitutive PSc promoter
• Targeted integration of your gene of interest into the Synechococcus elongatus genome
• Spectinomycin resistance gene for selection in Synechococcus
• pUC origin for maintenance in E. coli
