The present invention relates to a method for storage and subsequent lysis of a sample in which the sample is immobilized on a solid support. The solid matrix is embedded with a low concentration of both a chaotropic salt and a surfactant which act synergistically to efficiently store and lyse a biological sample.

Solid matrix for the storage of biological samples

The invention discloses a sample preservation method which comprises the following steps: a) providing a paper substrate comprising ligands, where the ligands comprise charged groups, b) applying a sample comprising at least one analyte and at least one contaminant on the paper substrate, c) drying the sample on the paper substrate and, d) extracting at least part of the paper substrate to provide a solution of the analyte.
