METHOD FOR PRE-PROCESSING MICRO AMOUNTS OF PARAFFIN-EMBEDDED CLINICAL BIOPSY TISSUE

摘要

Disclosed in the present invention is a method for pre-processing micro amounts of paraffin-embedded clinical biopsy tissue. The method comprises the following steps: 1) successively slicing a block of paraffin-embedded clinical biopsy tissue; 2) selecting a slice from among the slices of the same block of clinical biopsy tissue, and HE staining said slice to obtain a reference slice; 3) selecting a non-HE stained slice from among the slices of said same block of clinical biopsy tissue, and dewaxing so as to use as a slice from which tissue may be separated; 4) on the basis of the HE stain results of the reference slice, cutting tumor tissue off of the slice from which tissue may be separated.
