“…Immunoassays make it possible to measure trace components with high sensitivity and selectivity due to the high specificity of the antigen-antibody reaction (Gan and Patel, 2013;Marquette and Blum, 2009). Hence, it is used in a wide range of areas from basic to clinical research including, biological (Shim et al, 2017;Zong et al, 2012), environmental (Ahn et al, 2011), pharmaceutical (Han et al, 2013), and toxicological assays (Moody, 2006). Immunoassays can be categorized into several types depending on the way of analyte detection and differences in antibodies or antigens labeling (Marquette and Blum, 2009).…”
