A method for maldi - msi analysis of objects, in particular biological tissue samples, and the target for the analysis as well as its production

摘要

The object of the invention was in the case of the maldi - msi - analysis of an object of one or several analyte classes extensively as possible, with little effort and low duration of administration, without the signal quality with respect to intensity, localization and differentiability and without impairing the dyeing is possible for an optical scan of the tissue section to be reduced, wherein an exact histogram morpho logical comparability for a localization related evaluation analysis is to be made possible by means of engaging.According to the invention, a target (1), on which the object to be examined is to be applied, with a plurality of different matrix grids (2, 3) in the offset relative to one another in each case coated. For each matrix network (2, 3), at least one analysis grid in each case separately measured. The separately measured analysis grid specific data sets are in their entirety, as well as with object covering the same position reference evaluated.
