Application of Enzyme-Linked Immunosorbent Assay in Early Diagnosis of Cancer

As far as the current development of the medical community is concerned, early detection is the most effective way to deal with cancer, while enzyme-linked immunosorbent assay (ELISA) has been introduced in several diagnosis area of cancer for a long time. This research summarizes the usage of ELISA in various sections from the process of cancer’s early detection and highlights its function in the process of cancer’s early detection. There are several types of ELISA, this research focuses on indirect ELISA and sandwich ELISA, representing their special abilities that assist to complete the process of diagnosis of cancer. ELISA could be applied in both the detection of biomarkers and the antigen from the tumor cells, thereby helping to easier detect the existence of cancer. Moreover, ELISA is functional in data provision, which assists the construction of graphics as well as later treatments. Since ELISA could be applied in almost every section of the early detection of cancer, the development scope of its specific performance is extremely broad. Even though several problems constantly occur, the application scope of ELISA is still steadily expanding throughout the biomedical area.
