MAGDA™ Salmonella and Salmonella TAG 24 for 24 Hour Salmonella Results

Raisio Diagnostics now provides two alternative ways to achieve fast and reliable Salmonella results.

• MAGDA™ Salmonella
  For users preferring plating as the detection method Raisio Diagnostics offers a 24-hour method, MAGDA™ Salmonella. This novel test offers high sensitivity with low capital investment in instrumentation. Culture-based plating as a detection method makes for easy and familiar handling, just like ISO.
  
  The MAGDA Salmonella 24-hour method combines traditional plating with a unique immunomagnetic capture to shorten the enrichment time and have the results available in 24 hours as colonies on an agar plate. Proprietary enrichment supplement combined with shaking during incubation makes it possible to cut the enrichment time to only 5 1/2 hours. In order to have a representative sample, as much as 10 ml of culture is used. Hence a good sensitivity is achieved in less time. PickPen® technology enables effective immunomagnetic capture of bead-bacteria complexes by collecting the magnetic beads and removing them from the liquid. Plating on agar plates of the user's own choice is performed with the same PickPen device. It has a flexible silicon rubber tip that prevents the inconvenience of breaking the agar when plating and makes plating easy without any additional steps. Confirmation of positive colonies can be made in 16 hours after plating giving a total assay time of only 24 hours starting from the start of the enrichment.
  
• TRANSIA® Additive Gold 24
  TAG 24 is a supplement to the established TRANSIA® Salmonella Gold, an enzyme immunoassay widely used for testing of the Salmonella genus. It is a microtitration plate based assay with antibodies targeted against unique lipopolysaccharides (LPS). It works with a simplified two-step enrichment procedure where no M-broth is needed to stimulate flagella growth. The test is used for raw and processed food as well as feed and environmental samples.
  
  TAG 24 together with TRANSIA Salmonella Gold forms a complete testing facility. The first result is already available 24 hours from the start of enrichment. If a sample is positive, the confirmation by plating can be run directly from the same second broth as the TAG 24 to give a confirmed positive result.
  
  TAG 24 Salmonella Gold uses ELISA technology with absorbance measurement as the detection method. The same detection technology is also used for Salmonella Gold, so the same instrumentation can be used both for the 24-hour method and the 36-hour method. This gives extreme flexibility as to how samples and results are handled. The tests can also be run under full automation with the TRANSIA ElisaMatic II or TRANSIA 4U automated ELISA processors.
