Patent ID: 8911682

Claim:
A method for use with a plurality of animal or human donor tissue samples and a paraffin recipient block provided with a plurality of wells each having a cross-sectional size and shape to form a high yield tissue microarray block, comprising the steps of: cutting each one of said plurality of animal or human donor tissue samples into a plurality of tissue sample fragments, suspending each plurality of tissue sample fragments in a separate liquid carrier to form a two phase mixture of solid tissue sample fragments and liquid carrier for each plurality of tissue sample fragments, compacting each of said two phase mixtures of solid tissue sample fragments and liquid carrier into a chamber to take the form of a column for use in a high yield tissue microarray block, and transferring each of said columns from the chamber into at least one of said plurality of wells of said paraffin recipient block to create the high yield tissue microarray block, the chamber having a cross-sectional size and shape approximating the cross-sectional size and shape of the at least one of said plurality of wells, the length of each of said columns being independent of the size of the respective donor tissue sample.
