Figure 6From: Characterization and applications of Nanobodies against human procalcitonin selected from a novel naïve Nanobody phage display libraryDetection of PCT by the sandwich ELISA based on BiNb2. (A) The purified BiNb2 was analyzed by SDS-PAGE. (B) Schematic drawing of the proposed sandwich ELISA. (C) Calibration curve toward different concentrations of PCT. The linear relationship was in the range from 10 to 1000 ng/mL.Back to article page
