Figure 3

A trend plot of ion m/z 833.75 (MS −ve) (LIV 4) representing the abundance of the ion within each cut for all samples analysed by the REIMS technology. It demonstrates that the ion was only present in liver samples. However, the figure also clearly shows that the ion is not present within 4/11 (36%) of the liver samples analysed. Therefore, it cannot be considered a unique marker. Such observations maybe a result of sex, breed, geographic origin or feed.
