Principle

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 to remove salts, and finally DNA was eluted by Elution Buffer.

Advantages

• High binding force – suitable for handling DNA rich samples, such as whole blood, buffy coat, concentrated blood, etc.
• High purity – carboxyl magnetic beads with weak surface adsorption, getting higher purity
• General – can be used for various clinical samples

Storage and Stability

Proteinase K, MagBind Particles should be stored at 2–8°C upon arrival. However, short-termstorage (up to 18 weeks) at room temperature (15–25°C) does not affect their performance. The remainingkit 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 the determination of Escherichia coli in drinking water and its source water by multiple tube fermentation method.

Principle and Interpretation

MUG permits the rapid detection of Escherichia coli when the medium is observed for fluorescence using a UV light. MUG is hydrolyzed by the enzyme β-glucuronidase which is produced by E. coli to yield a fluorescent end product 4- methylumbelliferone. Trypticase provides the essential nutrients. Lactose is the fermentable carbohydrate. Sodium chloride maintains the osmotic equilibrium. The medium has a strong buffering system to control the pH in the presence of fermentative action. The bile salts inhibit gram-positive bacteria especially the Bacillus species and faecal Streptococci.

Formulation

Ingredients	/liter
Trypticase or tryptose	20 g
Bile salts No. 3	1.5 g
Lactose	5 g
K2HPO4	4 g
KH2PO4	1.5 g
NaCl	5 g
4-methylumbelliferyl-β-D-glucuronide (MUG)	50mg
pH6.9±0.2 at 25°C

Preparation

Weigh 37g of dry powder of this product, add 1L of distilled water or deionized water, stir, heat and boil until

completely dissolved,  sterilize at 115℃ for 20min, cool to room temperature and set aside.

Quality Control

The following quality control strains were inoculated and cultured at 44.5℃±0.5℃ for 24h. The results are as follows:

Quality control strains	Growth
Escherichia coli ATCC25922	Blue-white fluorescence is produced under 366nm UV light
Salmonella typhimurium ATCC14028	No fluorescence under 366nm UV light
Enterococcus faecalis ATCC29212	Clear, no fluorescence

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.
