Description
The DM3160 FluoroBand™ 1KB (0.25-10 kb) Fluorescent DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with high sensitivity DNA binding fluorescent dye and loading dye for direct gel loading. The DNA ladder DM3160 is composed of 13 individual DNA fragments: 10k, 8k, 6k, 5k, 4k, 3k, 2.5k, 2k, 1.5k, 1k, 750, 500, and 250 bp derived from a mixture of PCR products and specifically digested plasmid DNA; these bands can be visualized when illuminated with 470 nm blue light or UV light. This product contains two enhanced bands (3 kb and 1 kb) for easier reference. In addition, two tracking dyes, Xylene cyanol FF and Bromophenol blue which mimic the migration of 4,000 bp and 500 bp dsDNA during electrophoresis are also added for real time monitoring. Real time observation of the electrophoresis is also possible if compatible light source is fitted to the electrophoresis tank.

Toxoplasma gondii is a single-celled organism which causes Toxoplasmosis, the most common parasitic infection worldwide affecting animals as well as humans. Cats are the only animal in which sexual reproduction of the organism occurs, and for this reason cats are the only domestic animal which has the potential to shed T. gondii eggs. When disease does occur, it may develop following primary infection due to an inadequate immune response to stop the invasive tachyzoites or as a result of a reactivated infection due to a compromised immune system. The most common symptoms of the disease are anorexia, weight loss, lethargy, dyspnea, ocular symptoms and pyrexia. As toxoplasmosis can be transmitted to humans it represents a serious health risk for people living in close contact with infected animals. Infection is especially dangerous for people with suppressed immune systems and cancer patients as well as pregnant women.

Storage Conditions
All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
