초록

영어
Prostate-specific antigen (PSA) is a protein produced from the prostate gland. PSA is present in small quantities in the serum of normal men and is not present in the serum of normal women. However, the concentration of PSA is often elevated in the presence of prostate cancer and in other prostate disorders. Detecting abnormal concentration of PSA in the body is the main way for early discovery of the prostate cancer. There are two types of particles to detect pathogen in the enzyme amplification based bioassay, a magnetic microparticle(MMP) and an Au nanoparticle(AuNP). A MMP is functionalized with a monoclonal antibody which is attached by an affinity to a target of interest such as PSA, and an AuNP is funcionalized with an polyclonal antibody which is attached by an affinity to the same target of interest. The DIG-labeled
Oligonucleotides with thiol terminal group was covalently attached on the AuNP, and then HRP labeled anti-DIG was bound to DIG labeled DNA on AuNP. By this process, the number of HRP on AuNP could be enhanced and effectively act as reporter groups for the target of interest. The immobilized enzyme on AuNP probes is reacted with tetramethylbenzidine (TMB) that is a substrate of HRP, followed by stopping the reaction with 2M H2SO4. The resulting end products were analyzed by UV-vis spectroscopy.
