New technique for detecting cancer cells
26 December 2009Japanese researchers have recently developed a new technique for detecting cancer. Researchers first synthesized a protein that emits light in near IR region and thereafter conjugated the protein cell with therapeutic antibodies. The research findings have been published in the proceeding of 7th September 2009, of National Academy of Sciences of USA.
Researchers took a light emitting organic fluorescence dye of the species of cyridina noctiluca and with the help of this light emitting fluorescence dye synthesized a protein. Once there is any interaction between two compounds in the form of a vivo chemical reaction, some amount of energy is transferred from one to another and the dye emits near infrared light, as it can easily penetrate the living tissues, it can be monitored externally.
This is the first time when a light emitting protein is synthesized by researchers and moreover researchers demonstrated the nano liver cancer cells deliberately transplanted in the body of test animals, can be diagnosed and monitored with the help of near infrared light-emitting probe of a CCD camera. This is really a unique innovation, as it does not require conventional radiation techniques to detect and monitor the cancer cells.
