The low and unpredictable uptake and cytosolic transfer of oligonucleotides (ODN) is a major reason for their limited benefit. Improving the ODN potential for therapy and research requires a better understanding of their receptor-mediated endocytosis. We have undertaken to identify a membrane ODN receptor on HepG2 cells by ligand blotting of cell extracts with [I-125]ODN and by photolabelling of living cells with a [I-125]ODN-benzophenone conjugate. A major band at 66 kDa was identified by the two methods.
