Rodrigo F. Chuaqui has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8460744
    Abstract: 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.

  • Patent number: 7226731
    Abstract: 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 transcription 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.
