The number of individual trees per species used to perform the assay at each date is shown in parentheses. The numbers in parentheses are the number of animals assayed. The application of these assays to the current prevention strategies will simplify the prevention practice and rationalise the use of antibiotics. They compared linearity, ease of standardisation, precision, comparability of assay values, technical ease of the assay and cost.

Two functional assays have been used to examine the interactions between the probable upstream factors and the alpha-element. One of the proposed methods of detection is an antibody assay utilizing fluorescently labelled antibodies. The detection limit of the assay was 400 genome copies/ml. This transient assay allows rapid functional tests and is not dependent on the fastidious and time-consuming generation of stably transformed wheat plants. The assay has not only been appropriately validated, but also widely implemented across the entire country, servicing a 16.5 million strong population. The ineffectiveness of alternative protein phosphatase inhibitors to stimulate germination supports this possibility, but additional viability assays in the presence of these compounds are necessary.
