Matrix Microscience has announced that it has gained AOAC-RI approval for its salmonella Pathatrix 10 Pooling product.
Pathatrix 10 Pooling relies on 'post-enrichment pooling' as opposed to pre-enrichment sample compositing, and maintains 100 per cent sample integrity.
Matrix Microscience said the benefits of the Pathatrix Pooling strategy include: increased sample throughput; 90 per cent cost savings associated with end-point detection; labour savings; and compatibility with a range of end-point technologies.
The Pathatrix Pooling principle relies on the pooling of either 10 x 5ml or 10 x 25ml sub-samples to create a single 50ml (mini-ultra format) or 250 ml (ultra format) wet composite sample, which can be analysed by a range of end-point detection technologies.
In this way negative samples can be screened out efficiently and if a positive pooled sample is obtained then the original post-enriched samples, where complete sample integrity has been maintained, can be quickly re-analysed.
The company said the Pathatrix can be an effective tool for investigating contamination incidents and/or positive release scenarios.
