Intracellular Trafficking of Oligonucleotides. RGD-623-Tamra is a 2′-OMe-PS antisense oligonucelotide that has a 5′-RGD targeting ligand and a 3′-Tamra fluorophore. Its distribution in cells is compared to that of caveolin (A) or the avb3 integrin (B) (its receptor) as visualized by immunostaining. Fletchings indicate areas of overlap.
