IRDye® 800CW RGD Optical Probe (15 nmol)

IRDye 800CW RGD Optical Probe is a BrightSite™ near-infrared (NIR) fluorescently-labeled RGD imaging agent specifically designed to target the overexpression of integrins on tumors.

Integrins are cell surface heterodimeric glycoproteins involved in cell-to-cell and cell-to-matrix interactions. IRDye 800CW RGD Optical Probe is composed of the recognition motif, RGD (Arg-Gly-Asp), a tripeptide sequence used to bind integrin receptors including α_vβ₃. This receptor class is involved in tumor growth, tumor invasiveness, metastasis, tumor induced angiogenesis, inflammation, osteoporosis, and rheumatoid arthritis.

Interest in using a labeled RGD peptide ligand for the study and/or monitoring of diseases related to the α_vβ₃ receptor over-expression is increasing. Several groups have labeled RGD successfully with fluorescent dyes for in vitro and in vivo imaging.
