    摘要： A method of removing a target from a biological sample which involves placing a transfer surface in contact with the biological sample, and then focally altering the transfer surface to allow selective separation of the target from the biological sample. In disclosed embodiments, the target is a cell or cellular component of a tissue section and the transfer surface is a film that can be focally altered to adhere the target to the transfer surface. Subsequent separation of the film from the tissue section selectively removes the adhered target from the tissue section. The transfer surface is activated from within the target to adhere the target to the transfer surface, for example by heating the target to adhere it to a thermoplastic transfer surface. Such in situ activation can be achieved by exposing the biological sample to an immunoreagent that specifically binds to the target (or a component of the target). The immunoreagent can alter the transfer surface directly (for example with a heat generating enzyme carried by the immunoreagent), or indirectly (for example by changing a characteristic of the target). In some embodiments, the immunoreagent deposits a precipitate in the target that increases its light absorption relative to surrounding tissue, such that the biological specimen can be exposed to light to selectively heat the target. Alternatively, the immunoreagent is an immunofluorescent agent that carries a fluorophore that absorbs light and emits heat.

    摘要： A device for performing target activated transfer that includes a mounting surface for mounting a tissue sample; and a light source positioned to substantially uniformly irradiate both stained and unstained regions of the tissue sample with light energy that activates the reagent to selectively adhere the stained regions to a transfer surface. Also described is an automated system for transferring tissue from a tissue sample to a transfer substrate. The system includes means for holding a tissue section that includes targets specifically stained with an absorptive stain thereby resulting in a stained tissue surface, and a flexible transfer film that includes a lower thermoplastic layer in sufficient thermal contact with the stained tissue surface; an irradiating assembly configured to provide a predetermined uniform light dose to the entire tissue section; and means for applying a constant pressure to the transfer film during irradiation.

    摘要： A novel gene, PB39, that is up-regulated, or over-expressed, in prostate cancer has been identified. The gene has been identified by means of its cDNA obtained by reverse transcription of the corresponding mRNA. Microdissection of prostate glands that had been surgically removed from prostate cancer patients revealed a novel up-regulated transcript in an aggressive prostate carcinoma. Differential analysis for the presence of this gene was carried out from the same glands by comparing tanscription in microdissected normal prostatic epithelium versus that in microdissected invasive tumor. The transcript was over-expressed in 5 of 10 prostate carcinomas examined. A variant transcript was over-expressed in 4 of 4 prostate carcinomas, and was found in 1 of 4 normal samples. The invention provides a purified and isolated nucleic acid that includes the sequence of PB39 or its complement, the sequence of a variant of PB39 or its complement, and a primer or probe, that includes a sequence that is a fragment of these sequences. Additionally, the polypeptide encoded by these genes, an antibody to the polypeptide, and methods of detection of PB39 or its gene product are provided.
