Optic Chip Detecting Breast Cancer

The Microcirculation Institute of China Xiehe Medical University under the Chinese Academy of Medical Sciences applied the optic protein chip to test the TP in breast cancer cells and achieved the similar result produced by a testing method prevailed overseas. Chinese researchers have also worked out the preparation process for producing the anti—CA15—3 optic protein chip, a major lab testing indicator.

In the course of applying China's proprietary optic protein chip to test the TP in breast cancer cells and exploring anti — TP multi — cloned antibody based optic protein chip testing method, the Institute has tested 20 breast vessel cancer cases and produced a result extremely consistent with the result produced by ELISA, an advanced immunity testing approach widely applied abroad. Compared with ELISA process, China's optic chip has been proved simpler and more reliable with easier readout and lower cost, very promising for wide clinic applications. CA15—3 is an important serum protein indicator needed by breast cancer lab testing and post-operation tracking—down. Researchers employed the selected anti — CA15—3 monoclonal antibodies to make optic protein chips and applied them in testing 35 breast cancer patients  blood samples. The testing results have been compared with the one produced by the chemical CA15—3 testing process that is under the current clinic applications and shown the extreme relevance.

These findings have proved that China's proprietary optic protein chips are appropriate for mass production, given the merits such as easy and fast operation, low cost,  unified standards and find communication. Researchers expressed that if optic protein chips can be made clinically applicable together with associated testing equipment, a great advancement will be seen in improving clinic diagnosing and treating common diseases, post-operation tracking down and lowering medical expenses.
