Isothermal nucleic acid Principle Summary

The kit is based on room and constant temperature nucleic acid rapid amplification technology, its principle is that at room and constant temperature, the recombinase and primer form a protein/single-stranded nucleotide complex Rec/ssDNA, and invade the double-stranded DNA template with the help of auxiliary proteins and single-stranded binding protein SSB; then form a D-loop region at the invasion point and start to scan the DNA duplex, after finding the target region complementary to the primer and disintegration of the complex Rec/ssDNA, the polymerase also binds to the 3′ end of the primer to start the chain extension. The kit relies on the role of NFO enzyme and adds the designed specific molecular probes according to the template, and get the result by colloidal gold technology (sandwich method).

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.

Formulation

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

Cultural characteristics observed after incubation at 35-37°C for 46~50 hours

Storage and Shelf Life

2-30℃，Keep container tightly closed, avoid direct sunlight.

Use before expiry date on the label.

 Precautions

1. When weighing the dehydrated medium, please wear masks to avoid causing respiratory system discomfort

2. Keep container tightly closed after using to prevent clumping.

Waste Disposal

Microbiological contamination was disposed by autoclaving at 121°C for 30 minutes.

Introduction

HiPure Insect DNA Kits provides a simple and rapid solution for total DNA extraction of insect tissue samples. This kit is based on silica gel column purification technology without toxic phenol chloroform extraction and time-consuming alcohol precipitation. The whole extraction process only takes 30 minutes. HiPure Insect DNA Kit can process tissue samples less than 10mg at a time. Hipure Insect DNA 96 kit can process 96 insect tissue samples at a high throughput. The obtained DNA can be directly used in PCR, Southern blot, viral DNA detection and other experiments.

Details

Specifications

Principles

This product is based on silica column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).

Advantages

• High purity DNA – can be used in sensitive downstream applications such as multiplex and quantitative pcr
• Good repeatability – suitable for extracting high-yield DNA from insect tissue samples
• Safe – without phenol chloroform extraction and alcohol precipitation

Storage and Stability

Proteinase K, RNase A should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 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 at least 18 months under these conditions. The entire kit can be stored at 2–8°C, but in thiscase buffers should be redissolved before use. Make sure that all buffers areat room temperature when used.
