Fig. 4From: A novel detection methodology for HER2 protein quantitation in formalin-fixed, paraffin embedded clinical samples using fluorescent nanoparticles: an analytical and clinical validation studyExamples of HER2 testing images evaluated with PID and IHC. Images a-d is a classic negative example and images e-h is a classic amplified example. Images A and E are of bright field images; images B and F are of florescent PID images; images C and G are an overlay of fluorescent PID and the bright field images; images D and H are of HER-2 IHC-DABBack to article page
