4×4×96well Microplate Box Type Rotor

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

Ingredients	/liter
Enzymatic digest of casein	17.0g
Enzymatic digest of animal tissue	3.0g
Sorbitol	10.0g
Bile salt No.3	1.5g
Sodium chloride	5.0g
Neutral red	0.03g
Crystal violet	0.001g
Agar	15.0g
pH 7.1±0.2 at 25°C

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

Quality control strains	Growth	Colony color
Escherichia coli ATCC25922	PR≥0.7	pale pink to red
Escherichia coli 0157:H7 NCTC12900	PR≥0.7	colorless
Staphylococcus aureus ATCC 25923	Total inhibition	–

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.

Description

Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.

The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit.

Details of the target and priming specificity are included in the individual handbooks above.

Packaged, optimised and ready to use. Expect Better Data.

The Primerdesign™ genesig® Kit for Enterocytozoon bieneusi (E. bieneusi) genomes is designed for the in vitro quantification of E. bieneusi genomes. The kit is designed to have the broadest detection profile possible whilst remaining specific to the E. bieneusi genome. The primers and probe sequences in this kit have 100% homology with a broad range of E. bieneusi sequences based on a comprehensive bioinformatics analysis.
