Product news

Lab M (Bury, Lancs, UK), the microbiology culture media specialist, has introduced new variants of Fraser Broth – known as Fraser BrothPLUS – for the enrichment of Listeria species. The new products are designed to help overcome issues with conventional formulations when culturing organisms for subsequent ELISA analysis and they provide users with a valuable choice.

The presence of antagonistic compounds in conventional formulations appears to interfere with subsequent ELISA procedures by compromising the isolation rates of target organisms. With Lab M’s new ½ Fraser BrothPLUS and Fraser BrothPLUS, the antibiotic supplement is blended into the base medium, but the ferric ammonium citrate (FAC) component is supplied separately as a supplement. By separating the FAC from the base medium, it can be omitted for improved ELISA performance, or included for compliance with the ISO 11290 standard.

Fraser Broth is traditionally used as a secondary enrichment medium for the isolation of all Listeria species. With the incorporation of ½ strength supplement, it can also be used as a primary resuscitation or enrichment medium.

Cell / Tissue CultureCell culture or tissue culture is used to study the biology of cells or tissues and to isolate cellular products in an environment which can be manipulated and well defined. Accurately control your culture environment with bioreactors or culture incubators, bind your cells to a surface or together with an extracellular matrix. Distinguish cell types with differential media or proliferate cells with certain characteristics using selective media. Enrich your media with supplements such as growth factors, sera and vitamins.

ELISA often comes in kit format, with pre-selected antibody pairs to detect specific proteins or biomarkers of diseases such as diabetes and obesity, or cardiovascular and neurological disorders. Detection is made possible with chemiluminescent, fluorescent or colorimetric substrates and detection instruments such as microplate / ELISA readers. Other kits available include: Enzyme-linked immunospot (ELISPOT) assays for the quantification of protein-producing cells and chemiluminescent immunoassays (CLIA) kits.

Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.
