Schematic comparison of four different sandwich ELISA formats for human sEH detection using the same rabbit polyclonal anti-sEH as capture antibody, (a) format A: native nanobody and HRP labeled anti-HA tag IgG (VHH/HRP-anti-HA), (b) format B: biotinylated nanobody and HRP labeled anti-HA tag IgG (Biotin-VHH/HRP-anti-HA), (c) format C: biotinylated nanobody and streptavidin-polyHRP conjugate (Biotin-VHH/SA-PolyHRP), (d) format D: biotinylated nanobody and streptavidin-HRP conjugate (Biotin-VHH/SA-HRP), as detection antibody and tracer, respectively.
