Introduction

Intended Use

For enriching bile-tolerant Gram-negative bacteria in the microbiological examination of pharmaceutical products.

Principle and Interpretation

Pancreatic digest of gelatin provide protein, vitamins and amino acids; glucose carbon source; disodium hydrogen phosphate and potassium dihydrogen phosphate as a buffer; ox bile and brilliant green as selective antibacterial agent, inhibiting the growth of non-Enterobacteriaceae.

Formulation

Ingredients	/liter
Pancreatic digest of gelatin	10g
Glucose monohydrate	5g
Dehydrated ox bile	20g
Potassium dihydrogen phosphate	2g
Disodium hydrogen phosphate dihydrate	8g
Brilliant green	15mg
pH7.2±0.2 at 25°C

Preparation

Suspend 45g in 1L of distilled water,stir until completely dissolved and dispense 100 mL into test tubes , heat at 100 °C for 30 min in a waterbath or flowing steam.

Quality Control

The following quality control strains were inoculated and cultured at 30-35℃ for 24h-48h. The results are as follows:

Quality control strains	Inoculum (CFU)	Growth
Escherichia coli ATCC8739	< 100	Good growth
Pseudomonas aeruginosa ATCC9027
Staphylococcus aureus ATCC6538	> 100	Inhibited

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.

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. After adding magnetic particles and binding solution, DNA/RNA 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/RNA was eluted by Buffer NFW.

Advantages

• Fast – several samples can be extracted in 40 minutes by column method
• High quality – high purity total RNA / DNA can be directly used in various sensitive downstream applications
• Safe – no phenol chloroform extraction required
• Sensitive – DNA/RNA can be recovered at the level of PG

Storage and Stability

MagPure Particles and Proteinase K, DNase I  should be stored at 2–8°C upon arrival. However, short-term storage (up to 2 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 18 months under these conditions.
