Are you working on DNA-damage and repair? Would you be interested in a pre-validated cell-context system to analyze HR or NHEJ by single cell imaging or quantifying DNA repair by simple fluorescence?
TopoGEN, Inc. has developed a suite of cell lines that will allow you to study specific DNA repair pathways in living cells. Our systems report specific Homologous Recombination (HR) well as Non-Homologous End Joining (NHEJ) pathways. These engineered cell lines are truly novel, giving unprecedented insight into HR and NHEJ at a single cell level of resolution. DNA repair is activated using an inducible DNA damage event directed specifically at a neutral reporter gene. Moreover, since only repaired cells become fluorescent, the investigator can follow each individual cell (and all descendants) by live imaging.
Doctors don’t understand іt, but ѕоmе patients complain thаt thеіr antidepressants simply stop working оvеr tіmе. Known аѕ tachyphylaxis, іt іѕ a common reasons whу MDs switch patients tо оthеr medications оr add additional antidepressants tо existing treatments. Onсе аgаіn, tianeptine does nоt appear tо suffer frоm thіѕ all-too-common shortcoming. Thеrе іѕ, іn fact, ample evidence tо suggest thаt tianeptine actually grows mоrе effective thе longer іt іѕ taken. Sеvеrаl open long-term trials hаvе confirmed thаt thе efficacy оf thе tricyclic antidepressant actually increases wіth tіmе. Onе clinical trial fоund thаt аn astonishing 78 percent оf subjects wіth MDD responded favorably tо regular treatment wіth tianeptine. Here you will get the best Bloom Aesthetics Medspa, do visit. Furthermore, thе medication hаѕ proved a remarkably effective treatment option fоr depressed patients wіth anxiety. Tianeptine іѕ a prescription medication thаt treats bоth anxiety аnd depression, you can tianeptine buy here.
We offer certified cell lines hosting both HR and NHEJ in human and mouse species. There are neuron specific and fibroblast hosting lines with other cell lineages under development (cardiac, kidney, NCI-60 lines, IPSCs).
You can also provide us with your unique cell line to ‘host’ these repair systems (see our “Custom Services” program where we install an HR or NHEJ reporter in your specific cell line). Please contact us for a quote.

HR & NHEJ in same cell:
Multiplex Systems: Analyze HR (GFP) and NHEJ (YFP) in the same cell line (please enquire).
*Custom Kits allow you, the customer to create a project or disease specific cell line to host HR or NHEJ.
Alternatively, we can make the cell line for you (please enquire).
