Universal colorful staining of cancer tissues and normal tissues for histological diagnosis†
Abstract
The versatility of multicolor imaging of human tissues based on staining with perylene monoimide–mannose conjugates PMI-Man and co-staining with PMI-Man and eosin (P&E) was investigated for human cancer and normal tissues. Staining with PMI-Man or co-staining with PMI-Man and eosin showed a perfect histological morphology both in confocal fluorescence microscopy and light microscopy. This approach provided a universal colorful staining method for cancer tissues and normal tissues.
