New ultra sensitive test designed to detect diseases developed
Q. New ultra sensitive test designed to diagnose cancer and HIV has been developed and involves identification of ____ for discovering biomarkers.- Published on 21 Mar 16a. Flag
b. Atom
c. Molecule
d. None of the above
ANSWER: Flag
This test has been designed to detect deadly diseases including HIV and cancer, and it may prove 10,000 times more efficient than current diagnostic tools, according to Stanford scientists. The disease whether it is a cancer or virus like HIV begins growing in the body, so human beings respond by producing antibodies. Identifying the related biomarkers is a key to correctly diagnosing the disease. This involves designing a molecule which the biomarker is adorned with an identifying flag and through specialised chemical reactions called immunoassay, researchers can find the flag and the biomarker associated with it, providing proxy measure of the disease. The new technique developed by Professor C. Bertozzi of Stanford University replaces standard flag with short strand of DNA which can be treated out of sample using DNA isolation technologies far more sensitive than those possible for traditional antibody detection.
