For the selective isolation and culture of Listeria monocytogenes.
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.

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.
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 | – |
2-30℃，Keep container tightly closed, avoid direct sunlight.
Use before expiry date on the label.
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.
Microbiological contamination was disposed by autoclaving at 121°C for 30 minutes.

Description
The ExcelTaq™ 5X Fluorescent PCR Master Mix is a ready-to-use mixture for amplifying targeted DNA fragments. It is designed to serve as a master mix for virtually all PCR applications. This product is supplied as a 5X concentrated mixture containing all the essential ingredients for PCR with the exception of templates and primers. In addition, the mixture contains electrophoresis tracking dye (Bromophenol blue) and a safer fluorescent DNA staining dye, which enables the user to track the electrophoresis process in real time as well as eliminates the need for the staining process. The resultant PCR reaction mixture is sufficiently dense enough to be loaded directly into a TAE or TBE buffered gel for electrophoresis.
