Listeria monocytogenes have emerged as significant foodborne pathogens that pose a serious public health problem. As the causative agent of Listeriosis, L. monocytogenes has the highest rate of fatality rate among all foodborne pathogens. L. monocytogenes is a facultatively intracellular, Gram-positive bacterium that could survive high and low temperatures, low pH. It is a rare causative agent of mastitis in cow. However, due to its ability to resist various food processing technologies as well as to grow at low temperature, L. monocytogenes is know to be associated with both raw and pasteurized milk, as well as dairy products such as cheese. As little as 1000 organisms may cause the disease with pregnant, new-born, and immunocompromised individuals the most susceptible.
The Listeria monocytogenes TaqMan PCR Kit Dx is shipped on dry ice. The components of the kit should be frozen upon arrival. If one or more of the components is not frozen when the kit is received, or if any of the components have been compromised during shipment, please contact Norgen Biotek for assistance. All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 3 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.

Main Functions
Rapidly Extract viral DNA/RNA from 200μl non-cell/low cell content biological samples such as body fluid, serum, plasma, urine, immersion solution, tissue homogenate supernatant, etc.
This product is based on silica gel purification. The sample is lysed and digested with lysate and protease, DNA/RNA is released into the lysate. Transfer to an adsorption plate and filter column. DNA/RNA is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, DNA / RNA was finally eluted with low-salt buffer (10 MmTris, pH 8.0).
Advantages
Fast – column purification without PK digestion
High quality – high purity total RNA can be directly used in various sensitive downstream applications
Safe – no phenol chloroform extraction required
Sensitive – DNA/RNA can be recovered at the level of PG

Storage and Stability
Proteinase K should be stored at 2–8°C upon arrival. However, short-term storage (Proteinase K up to 8 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15–25°C) and are stable for 18 months under these conditions.
