Detail

Overview

  • Quantified standard to be used as a positive control or PCR quantification standard
  • Vigorously quantified using multiple methods

Listeria monocytogenes has emerged as a significant foodborne pathogen that poses a serious public health problem. As the causative agent of Listeriosis, L. monocytogenes has the highest rate of fatality among all foodborne pathogens. L. monocytogenes is a facultatively intracellular, Gram-positive bacterium. Due to its ability to survive high and low temperatures as well as low pH, it could resist various food processing technologies, as well as grow at food storage temperatures. L. monocytogenes is known to be associated with raw meat, unpasteurized milk and dairy products, vegetables, and seafood. As little as 1000 organisms may cause the disease with pregnant, new-born, and immunocompromised individuals being the most susceptible.

Norgen’s Listeria monocytogenes Quantified Bacterial DNA Standard is prepared from cultured bacteria using Norgen’s sample preparation technology. The purified DNA is quantified vigorously using multiple methods including spectrophotometry, gel densitometry and real-time PCR. It is intended to be used as a positive control or PCR quantification standard for Listeria monocytogenes.

Description

Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.

The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit.

Details of the target and priming specificity are included in the individual handbooks above.

D3139 HiPure Insect DNA 96 Kit

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.

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.
