    Productomschrijving

    The Escherichia coli detection kit is based on the fast, sensitive, and proven primers/probe qPCR technique. The kit contains primers and a probe for detecting a highly specific sequence (uidA gene) present on the DNA of the species Escherichia coliThis kit of Sylphium molecular ecology is designed to have a sensitivity of only one molecule per reaction in environmental samples.

    Toxin information
    Escherichia coli, also known as E. coli , is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms (endotherms).Most E. coli strains are harmless, but some serotypes can cause serious food poisoning in their hosts, and are occasionally responsible for product recalls due to food contamination.

    Primer design

    Primers and probe and the qPCR buffer were designed to have:

    • •Highest possible sensitivity (1 DNA copy per reaction). Environmental water samples contain normally very low amounts of target DNA.
    • Strong fluorescence signal with low background noise. Isolated environmental samples contain residues of naturally occurring auto fluoresce substances that will interfere with the measurements. A strong fluorescence signal from the analyses is required for these kind of samples.
    • 100% specificity. Isolated DNA from environmental samples contains billions of DNA fragments from bacteria, protozoa, plants, animals, etc.

    The kit is developed and optimized to be used on eDNA isolates purified using the eDNA isolation kit (#SYL002) from Sylphium molecular ecology.

    Kit contents
    The kit contains materials for an 3-fold analyses on 36 samples including all necessary controls.
