For the selective isolation and culture of Listeria monocytogenes.
Principle and Interpretation
Peptone provides the carbon and nitrogen sources necessary for growth; yeast extract powder and starch provide carbon and nitrogen sources, vitamins and growth factors; sodium chloride can maintain a balanced osmotic pressure; glucose provides a carbon source; Listeria hydrolyzes esculin and reacts with iron ions to form black 6,7-dihydroxycoumarin; mannitol is a fermentable sugar, and phenol red is a pH indicator; lithium chloride and other antibiotics can inhibit Gram-negative bacteria and most Gram-positive bacteria; agar is the coagulant of the culture medium.

Main Functions
Isolation total DNA from 50-100 mg plant, fungal tissue
Applications
PCR, transgene detection, fluorescence quantitative PCR, southern blot, SNP site analysis, etc.
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 toremove salts, and finally DNA was eluted by Elution Buffer.
Advantages
Safe – require no phenol or chloroform extraction
Fast – several samples can be extracted in 60 minutes
High purity – high quality DNA, completely remove inhibitors

Storage and Stability
RNase Solution and 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.
