Optimization strip test of using 4 kinds rewetting agents. A = PVP; B = PEG-2000; C = BSA; and D = Rhodasurf® On-870 (a).—= 0 ng mL−1 and + = 20 ng mL−1. Results after optimization to detect PRO in 0.01 M PBS using LFLM (b), 1–9 represents concentration of 0, 0.25, 0.5, 1, 2.5, 5, 10, 25 and 50 ng mL−1. C = control line. T = test line
