Figure 4From: In vivo optical imaging of integrin αV-β3 in mice using multivalent or monovalent cRGD targeting vectorsConfocal laser scanning microscopic images of HEK293(β3) s.c. tumors dissected at 3 hr after i.v. injection of 10 nmol Cy5-labeled RAFT-c(-RGDfK-)4 (A, B), cRGD (C), or RAFT-c(-RβADfK-)4 (D). Paraformaldehyde-fixed cryosections were incubated with Hoechst 33342 for nuclear staining (blue). Signal from Cy5 was pseudocolored red. Original objective: Plan-Apochromat 63x/1.4 Oil; an additional zoom of 4x was added for the insert in B.Back to article page
