Echinococcus multilocularis (Em18) – IgG ELISA

Introduction

Intended Use

For the selective isolation and culture of Listeria monocytogenes.

Principle and Interpretation

Peptone provides the carbon and nitrogen sources necessary for growth; yeast extract powder and starch provide carbon and nitrogen sources, vitamins and growth factors; sodium chloride can maintain a balanced osmotic pressure; glucose provides a carbon source; Listeria hydrolyzes esculin and reacts with iron ions to form black 6,7-dihydroxycoumarin; mannitol is a fermentable sugar, and phenol red is a pH indicator; lithium chloride and other antibiotics can inhibit Gram-negative bacteria and most Gram-positive bacteria; agar is the coagulant of the culture medium.

Formulation

Preparation

Weigh 68.9g of dry powder of this product, add 1L of distilled water or deionized water, stir, heat and boil until completely dissolved, divide into Erlenmeyer bottles, sterilize at 121℃ for 15min, cool to room temperature and set aside. Heat to dissolve agar before use, cool to 50℃, add 1 tube of supporting reagent (SR0140) per 100mL of basal culture medium, shake well and pour into sterilized culture dish.

Quality Control

The following quality control strains were inoculated and cultured at 35-37℃ for 24h. The results are as follows:

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.

Intended Use For the selective isolation and culture of Listeria monocytogenes. Principle and Interpretation Peptone provides the carbon and nitrogen sources necessary for growth; yeast ex……

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).

Isothermal nucleic acid Product Features

1/ High sensitivity and specificity, short reaction time.

2/ The reagent form is freeze-dried, stable and easy to operate.

3/ The reaction can be operated by metal bath and water bath pot without purchasing expensive PCR apparatus.

Technical Parameters:

Isothermal nucleic acid Applications

Suitable for DNA isothermal rapid amplification kit(NFO type)

Primer: Require pair of nucleotide primers with the length of 25-35 bp.

DNA basic kit reaction temperature is 39 to 42℃ and time is 5-20 minutes.

Notes

1/ Please avoid nucleic acid contamination and set blank control during reaction due to the high sensitivity of the kit.

2/ Please take out the required quantity of MIRA reaction units for the experiment, and put the rest under storage conditions when performing the experiment.
