Introduction

Intended Use

For the detection of Salmonella spp. in food, animal feed and in environmental samples from the food production area as described in ISO 6579-1:2017.

Principle and Interpretation

Meat extract and casein provide a source of nitrogen and amino acids and sodium chloride maintain theosmotic balance. Ox bile and brilliant green act as selective agents against non-target microorganisms. Tetrathionate is generated from the sodium thiosulfate. Iodine and calcium carbonate buffer the sulfuric acid generated from tetrathionate reduction.

Formulation

Ingredients	/liter
Meat extract	4.3g
Enzymatic digest of casein	8.6g
Sodium chloride	2.6g
Calcium carbonate	38.7g
Sodium Thiosulfate (anhydrous)	30.4g
Ox bile	4.78g
pH8.0±0.2 at 25°C

Preparation

Suspend 89.4g in 1 L of purified water. Heat with frequent agitation and boil to completely dissolve the powder. Distribute into flasks，and then cool to below 45°C. Add a vial of novobiocin sodium salt (SR0640), a vial of iodine solution and a vial of brilliant green (SR0040) into 100 mL of base medium. Mix thoroughly.

Quality Control

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

Quality control strains	Approx. Inoculum(CFU)	Expected Results
Salmonella typhimurium  ATCC14028	10 – 100	≥ 10 cfu on XLD
Escherichia coli  ATCC25922	> 104	≤100 cfu on TSA
Enterococcus faecalis ATCC29212	> 104	<10 cfu on TSA

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.

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).

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.

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.

Introduction

The Kit is specially designed for simultaneous purification of genomic DNA and total RNA from formalin-fixed, paraffin-embedded (FFPE) tissue sections. The Purified DNA/RNA is used for RT-PCR and PCR detection.

Details

Specifications

Features	Specifications
Main FunctionsC	Co-isolation DNA and RNA from a single FFPE tissue sample
Applications	RT-PCR, cDNA synthesis, PCR and second-generation sequencing, etc.
Purification method	Mini spin column
Purification technology	Silica technology
Process method	Manual (centrifugation or vacuum)
Sample type	FFPE slice, FFPE embedded tissue
Sample amount	No more than six 10µm sections of 150mm2 surface area or three 20µm sections of 150mm2 surface area.

Principle

FFPE samples are incubated in an optimized lysis buffer, which results in the release of RNA and precipitation of DNA. After centrifugation, the RNA-containing supernatant and DNA-containing pellet are then processed separately to purify RNA and DNA. For RNA purification, transfer RNA Lysate to an adsorption column and RNA is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, RNA was finally eluted with low-salt buffer. For DNA purification, transfer DNA Lysate to an adsorption column and DNA is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, DNA was finally eluted with low-salt buffer.

Advantages

1.Use non-toxic dewaxing solution without contact with xylene
2.Obtain both DNA and RNA simultaneously from the same sample. Elute separately without affecting each other (Have the same steps and effects as top brand 80234, perfect substitute.)
