“…Furthermore, the CMIA method anchors antibodies via magnetic microparticles, a fact that makes this analytical method advantageous compared to ELISA assays. In particular, CMIA requires less dose of immunoreagents and time, while it provides a higher dose hook effect and bioactivity of immunoreagents as well as higher sensitivity, better reproducibility, and stability (Zhang et al 2012;Liu et al 2013).…”

“…Other immunoreaction‐based methods, such as surface plasmon resonance (SPR) or surface‐enhanced Raman scattering (SERS), required complicated and expensive instruments that made them difficult in practical diagnosis screening. Chemiluminescent immunoassay (CLIA) including chemiluminescence enzyme immunoassay (CLEIA) and electrochemiluminescence have been developed and adopted in routine clinical analysis for the high sensitivity determination of TPSA or FPSA. However, almost all of the aforementioned methods are either only for the detection of TPSA or only for the measurement of FPSA, which usually results in unmatched F/T ratios .…”

“…1,2 In blood, total PSA (tPSA) is composed of free PSA (fPSA) and complexed PSA (cPSA), and the ratio of fPSA and tPSA was found to be a more sensitive marker of cancer than tPSA. 3,4 Over the past years, several analytical methods have been developing in this area of the serum determination of PSA, including the enzyme-linked immunosorbent assay (ELISA), 5 radioimmunoassay (RIA), 6 Time-resolved fluoroimmunoassay (TRFIA), 7 chemiluminescence immunoassay (CLIA), 8 chemiluminescent enzyme immunoassay (CLEIA), 9 and electro chemiluminescence immunoassay (ECLIA). 10 Here we describe a combination of one-step dual-label TRFIA and magnetic beads to establish a new immunoassay method for the simultaneous detection of fPSA and tPSA in serum with monoclonal antibodies (mAb) labeled with stable fluorescent chelates of europium (Eu) and samarium (Sm).…”
