Figure 5. MAb476-based Lateral flow immunochromatographic assay device (LFD) detects Galf antigen in simulated and human urine samples.

Figure 5

A, appearance of the assembled LFD; subsequent panels show scanned images of the reaction window. B, Comparison of urine and normal saline (NS) as diluent for EPA293 in LFD. C, Detection of EPA293 in simulated samples after concentration (5–10 folds, 3 KDa MWCO) and desalting (7 KDa MWCO), compared to no treatment. D, Detection of Galf-containing antigen in processed clinical urine samples; 2 patients have intermediate (++) positive signal and 2 have weak (+) positive signal.
