The anti-cTnI mAbs could stain Huh-7 cells, MHCC-97L cells and MHCC-97H cells by IF. A-C: Representative confocal images of Huh-7 cells (bar = 40 μm). A: Negative control. B, C: Huh-7 cells were stained for cTnI (Fluorescein Avidin DCS, green) using 2F6.6 and XY15 mAbs, which recognized epitopes embodied at 13-36 and 56-80, respectively. D-F: Representative confocal images of MHCC-97L cells (bar = 40 μm). D: Negative control. E, F: MHCC-97L cells were stained for cTnI (Fluorescein Avidin DCS, green) using 2F6.6 and XY15 mAbs, which recognized epitopes embodied at 13-36 and 56-80, respectively. G-I: Representative confocal images of MHCC-97H cells (bar = 40 μm). G: Negative control. H, I: MHCC-97H cells were stained for cTnI (Fluorescein Avidin DCS, green) using 2F6.6 and XY15 mAbs, which recognized epitopes embodied at 13-36 and 56-80, respectively.
