Introduction

This product provides a fast and easy way to purify DNA from plant and fungal tissue. Up to 100 mg of tissue can be processed. Easy-to-use Plant procedures provide pure total DNA (genomic,mitochondrial, and chloroplast) for reliable PCR and southern blotting in less than 1 hour. Purification requires no phenol or chloroform extraction oralcohol precipitation and involves minimal handling.

Principle

Plantmaterial is first mechanically disrupted and then lysed by addition of lysis buffer and incubation. RNase A in the lysis buffer digests the RNA in the sample. After lysis, proteins and polysaccharides are salt-precipitated.Binding buffer and ethanol are added to the cleared lysate to promote binding of the DNA to the HiPure membrane. The sample is then applied to a column and then centrifuged. DNA binds to the membrane, while contaminants such as proteins and polysaccharides are efficiently removed by 2 wash steps. Pure DNA is eluted in a small volume of low-salt buffer or water.

Advantages

• Safe – require no phenol or chloroform extraction
• Fast – several samples can be extracted in 30 minutes by silica technology
• High purity – high quality DNA, completely remove inhibitors
• High yield – silica technology can achieve the highest yield

Storage and Stability

RNase A 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 its 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.

Introduction

Intended Use

For selective enrichment culture of Listeria monocytogenes in food.

Principle and Interpretation

Tryptone, proteose peptone, meat extract, yeast paste powder provide nitrogen sources, vitamins, amino acids, and growth factors; sodium chloride can maintain a balanced osmotic pressure; sodium dihydrogen phosphate and potassium dihydrogen phosphate as buffering agents; esculin are fermentable sugars; lithium chloride and other antibiotics can inhibit Gram negative bacteria and most Gram positive bacteria.

Preparation

Suspend 57.4g in 1 L of distilled or deionized water. Heat with frequent agitation and boil to completely dissolve the powder. Distribute into flasks. Autoclave at 121℃ for 15 minutes. Cool to 45-50℃,aseptically add the contents of 1 vial of Fraser Selective Supplement (SR0120) to each 225 mL of base to prepare FB1 solution; Add one reagent (SR0130) to each100 mL of FB2 culture medium to prepare FB2 enrichment solution.

Quality Control
