Detail
Introduction
Intended Use
Used for the selective isolation and culture of Listeria monocytogenes.
Principle and Interpretation
Columbia Blood Agar Base provide carbon and nitrogen sources, vitamins and growth factors，maintains balanced osmotic pressure; Listeria hydrolyzes aesculin and reacts with iron ions to form black 6,7-dihydroxycoumarin; lithium chloride and other antibiotics can inhibit Gram-negative bacteria and most Gram-positive bacteria; agar is the coagulant of the culture medium.
Formulation
Ingredients
/liter
Columbia blood agar base
39.0 g
Aesculin
1.0 g
Ferric ammonium citrate
0.5 g
Lithium chloride
15.0 g
pH7.0±0.2 at 25°C
Preparation
Weigh 55.5 g of this product, add 1000 mL of distilled water or deionized water, stir, heat and boil until completely dissolved, divide into Erlenmeyer bottles, sterilize at 121℃ for 15 min. Cool to about 50℃, add 1 bottle of SR0500 supporting reagent A and 1 bottle of B per 100 mL, mix well and set aside.
Quality Control
The following quality control strains were inoculated and cultured at 35-37℃ for 24h. The results are as follows:
Quality control strains
Growth
Listeria monocytogenes ATCC19115
Gray-green colonies with a black depression in the center and black surrounding
Enterococcus faecalis ATCC29212
–
Escherichia coli ATCC25922

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

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.
