  Bladder cancer is a heterogeneous disease and occupies highest incidence in developed country. Time-resolved fluoroimmunoassays (TRFIA) is a new detection technique with a feature of sensitive, simple and inexpensive. The aim of this study is to establish a dual-label TRFIA for the simultaneous detection of BLCA-4 and NMP52 in urine in a single run. The sandwich immunoassay was used to detect the concentration of BLCA-4 and NMP52 in urine. BLCA- 4 and NMP52 in urine were captured by anti-BLCA-4 and anti-NMP52 antibodies immobilized on microtiter wells, and then banded together with another anti-BLCA-4 and anti-NMP52 labeled with europium(III) Sm3+ and samarium(III) Eu3+ chelates, followed by fluorescence measurement using time resolved fluorometry. To assess the performance of this assay, clinical urine samples were used, and then commercialized kits were compared. The sensitivity for.. Read More»
