Detection of CPS in melioidosis patient serum and urine samples by antigen capture ELISA. For each ELISA, MAb 3C5 was used in the capture phase, followed by addition of serial diluted patient serum (1:2 starting dilution) and urine (no dilution to start) samples. HRPO-labeled MAb 3C5 was then used in the indicator phase to detect captured CPS. The titer of each of the clinical samples is listed in Table 1.
