Abstract
A visualization system for identifying a biological sample in a preservative solution comprising a dye that (i) colors a biological sample in a manner in which the sample can be readily identified and retrieved from among the other contents of the medium; (ii) provides a colored sample that permits proper positioning of the material in a paraffin block prior to sectioning; and (iii) does not interfere with the subsequent processing of the sample at the processing laboratory.
Claims19
A method for preparing a biological sample for examination, comprising adding a gross biological sample containing biological material selected from the group consisting of a tissue and an organ to a preservative medium which contains a visualization-effective amount of a dye that colors said gross sample in a manner in which said gross sample is visually identifiable for retrieval from among other contents of said medium and does not interfere with subsequent sectioning and staining of said gross sample for microscopic examination;
- identifying and retrieving the gross sample from the medium based on the resulting color differentiation;
- sectioning the gross sample to obtain an examination sample;
- and
- staining the examination sample.
A method for preparing a biological sample for examination, comprising adding a gross biological sample containing cells to a preservative medium which contains a visualization-effective amount of a dye that colors said gross sample in a manner in which said gross sample is visually identifiable for retrieval from among other contents of said medium and does not interfere with the subsequent staining of said gross sample for microscopic examination;
- identifying and retrieving the sample from the medium based on the resulting color differentiation;
- placing the sample on a support for examination;
- and
- staining the sample for examination.
