Abstract
Abstract An identification marker (17) is described for use in permanently identifying an individual histology sample (21), the marker including columnar indicia (18) mounted on a base (19) having a location flange (20). A specially adapted cassette having a slot (16) to receive the identification marker is described together with apparatus and method for moulding the indicia in a protein such as agar agar. The use of the identification marker is described firstly mounted in the cassette (11) during treatment of the sample (21) and later mounted beneath the cassette (11) in the slot (16) for wax embedding of the sample and identification marker. The marker (17) is sectioned simultaneously with the tissue sample (21) by means of a microtome (31), each section taken being identified by a section through the identification marker embedded alongside the sample.

Claim 1
Independent Claim
63 words
An identification marker for use in permanent identification of a histology sample comprising a plurality of columnar indicia moulded integrally with a base, the indicia extending from the base in a protruding manner, the marker consisting solely of a single mouldable jelly-like material capable of being sliced by microtome and dimensionally sized for embedding within an embedding medium along with a histology sample.
Claim 2
Dependent Claim
63 words
An identification marker for use in permanent identification of a histology sample comprising a plurality of columnar indicia moulded integrally with a base, the indicia extending from the base in a protruding manner, the marker consisting solely of a single mouldable jelly-like material capable of being sliced by microtome and dimensionally sized for embedding within an embedding medium along with a histology sample.
Claim 3
Dependent Claim
13 words
