H&E + invisible IHC images using the dual-camera microscope system ( A ) and single-camera microscope system ( B – D ). ( A ) Dual-camera microscope monitor screenshot simultaneously displaying visible H&E staining (left side, color camera video) and non-visible LAG3 sCy7 IHC staining (right side, monochrome camera video) of melanoma FFPE tissue. The specimen was simultaneously illuminated with white light from a tungsten microscope lamp through a broad white light filter (420–620 nm) and NIR light from a 770 nm LED. ( B , C ) Sequential view of H&E staining ( B ) and non-visible HER2 IHC using ir870 chromogen ( C ), on breast tumor FFPE tissue, using same color camera (IR-blocking filter removed). The specimen was illuminated with a tungsten microscope lamp while switching between the broad white light filter ( B ) and an 880 nm bandpass filter ( C ). ( D ) HER2 image displayed in grayscale (blue color plane of color image in part C ). Circles highlight two individual cells in images of each specimen. The color saturation of ( C ) was reduced to 60% to aid in viewing the printed blue image.
