a) obtaining a fresh residual surgical sample having a diameter of at least 1 cm at its widest point;
b) preparing a fixed but not paraffin embedded residual surgical sample for homogenization, wherein the preparation consists essentially of contacting the obtained fresh residual surgical material with a fixative; and
c) mechanically blending the prepared fixed but not paraffin embedded residual surgical sample to provide the representative sample, wherein any heterogeneity of cells within the prepared fixed residual surgical sample is substantially homogeneously distributed within the representative sample, and wherein any aliquot removed from the representative sample comprises one or more populations of subclones at a proportion at which they existed within the obtained fresh residual surgical sample.
