CAS: 251903-93-2

Luc-coliforms Na is a high quality, chromogenic substrate for the detection of coliforms. It is used widely in the food industry to detect whether coliforms are present in milk, cheese, and other dairy products. Luc-coliforms Na provides a color change from yellow to blue when it reacts with coliforms and has a high pH range of 4.0-8.0. Luc-coliforms Na has a CAS number of 93824-43-4.

Luc-coliforms Na is a fluorogenic substrate that is used in the diagnosis of bacterial contamination. It is a conjugate of the enzyme luciferase and the substrate coelenterazine, which are combined in a buffer solution. Luc-coliforms Na is used to detect bacteria by adding it to a culture broth or other growth media. The bacteria will emit light as they break down the luc-coliforms Na and produce ATP, which can then be measured with an appropriate detector. Luc-coliforms Na can also be used as a stain for gram-negative rods, such as coliforms, e.g., Escherichia coli, Enterobacter aerogenes, Klebsiella pneumoniae, Proteus mirabilis.
