Filamentous phage was labeled with QDs and its infective capability is observed after labeling. The experimental result shows that the labeling phage can still infect E.coli K91 normally. We have also developed the procedures for using QDs to label CHO-IR cells and Mouse Kidney tissue slice. The tissue slice remained stably labeled for over 10 d and the cells remained stably labeled even for over 5 months.展开更多
