Overview

• Detection kits for Listeria monocytogenes
• CE-IVD marked version available for in vitro diagnostic use
• Available in TaqMan format for analysis.

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.

Storage Conditions and Product Stability
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.

Introduction

This product provides fast and easy methods for purification of total DNA for reliable PCR and southern blotting. Total DNA(e.g., genomic, viral, mitochondrial) can be purified from whole blood, plasma, serum, buffy coat, bone marrow, other body fluids, lymphocytes, cultured cells.

Relevant reagents were pre-packed in 96-well plates in accordance with the optimal protocol.

Principle

This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and Protease. DNA is released into the lysate. After adding magnetic particles and binding solution, DNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally DNA was eluted by Elution Buffer.

Advantages

• High binding force – suitable for handling DNA rich samples, such as whole blood, buffy coat, concentrated blood, etc.
• Fast – polydisperse magnetic beads, fast magnetic response and short extraction time
• High purity – the obtained DNA can be directly used for second-generation sequencing, PCR based detection, gene bank, etc.
• Automatic – saving time andlabor and safer

Storage and Stability

Proteinase K, MagPure Particles should be stored at 2-8°C upon arrival. However, short-term storage(up to 24 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions.The entire kit can be stored at 2-8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.
