Introduction

Intended Use

For the isolation and differentiation of sorbitol-negative Escherichia coli serotype O157 from food and animal feed and other materials

Principle and Interpretation

Enzymatic digest of casein and enzymatic digest of animal tissue provides nitrogen source, vitamins and growth factors; sodium chloride maintains balanced osmoticpressure; sorbitol is a fermentable sugar; No. 3 bile salt and crystal violet inhibit Gram-positive bacteria, potassiumtellurite inhibits non-o157 Escherichia coli, and cefixime inhibits Proteus; neutral red is a pH indicator; and agar is the coagulant of the culture medium.

Formulation

Preparation

Weigh 51.5g of this product, add 1L of distilled water or deionized water, stir, heat and boil until completely dissolved, dispense into Erlenmeyer flasks, and sterilize at 121℃ for 15min. Melt the sterilized culture medium and cool it to about 45℃, add 1 tube of supporting reagent (SR0240) (0.25mg potassium tellurite and 0.005mg Cefixime) to every 100mL of basal culture medium, mix and pour into the plate.

Quality Control

Cultural characteristics observed after incubation at 35-37°C for 18-24hours

Sorage and Shelf Life

Keep container tightly closed, store in a cool, dry place, away from bright light. Storage period of 3 years.

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

The Kit provides fast purification of high-quality DNA, RNA and Prote from cells, tissues, and yeast using silica-membrane spin columns with a binding capacity of 100ug RNA. There is no need for phenol/chloroform extractions and time-consuming steps such as CsCl gradient ultracentrifugation, or precipitation with isopropanol or LiCl are eliminated. RNA purified using the HiPure Total RNA Purification System is ready for applications such as RT-PCR, Northern blotting, poly A+ RNA (mRNA) purification, nuclease protection, and in vitro translation.

Specifications

Principle

The Kit isolates total RNA from up to 10 ⁷ cells or 30 mg tissue. A short workflow enables RNAisolation with genomic DNA removal in less than 25 min. Samples are first lysed and homogenized. The lysate is passed through a DNA Mini column, ethanol is added to the flow-through, and the sample is applied to an RNA column. RNA binds to the membrane and contaminants are washed away. High-quality RNA is eluted in as little as 30 µl water using the Kit.

Advantages

• High quality – high purity total RNA / DNA can be directly used in a variety of downstream applications
• Fast – column method can complete the extraction of several samples in 30 minutes
• Safe – no phenol chloroform extraction required
• Simultaneous extraction- simultaneously isolate DNA and RNA from one sample

Storage and Stability

HiPure Kit can be stored dry at room temperature (15–25°C) and are stable for at least 18 months under these conditions. During shipment, crystals or precipitation may form in the Buffer RLC. Dissolve by warming buffer to 37°C.

Overview

• Detection kits for Legionella sp.
• Available for TaqMan format for analysis

Norgen’s Legionella sp. TaqMan PCR Kit is designed for the detection of Legionella sp. specific DNA in a real-time PCR based on the use of TaqMan technology. This kit is designed for research use only and not for use in diagnostic procedures. The detection of Legionella sp. specific DNA is based on TaqMan PCR providing a simple, reliable and rapid result for the detection of Legionella sp. infection. Norgen’s Legionella sp. TaqMan PCR Kit includes a PCR control to monitor for PCR inhibition, and to validate the quality of the sample and the detection result. The Legionella sp. TaqMan PCR Kit comprises Master Mix for the target and PCR control detection, Primer & Probe Mix, as well as a positive control and a negative control (nuclease-free water) to confirm the integrity of the kit reagents.

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.
