The selective listeria express enrichment (LEE) broth range from Lab M is designed to enhance expression of target antigens for downstream testing.
Developed to give improved growth rates of listeria over traditional selective enrichment media, the LEE broth range enhances the expression of target antigens for most commercially available immunological test methods while maintaining suppression of non-target organisms, Lab M claims.
Key to both the efficacy and convenience of the LEE broth is the blending of selective components directly into the medium, eliminating any need for supplementation.
It is formulated to stimulate growth from low numbers of organisms in the original sample to achieve the high levels required for further testing within a 24-hour incubation period.
Additionally, the range is ideal for enrichment prior to plating on selective media such as harlequin listeria chromogenic agar and it is also effective as a secondary selective enrichment broth following primary enrichment in half fraser broth, for example.
Lab M has also stated it performs well as the enrichment step for subsequent rapid testing in ELISA, lateral flow devices or PCR, for example.
As well as the LEE broth, the portfolio of media available from Lab M for listeria testing now includes harlequin listeria chromogenic agar, available as dehydrated culture medium or as ready-to-use prepared plates.
