| Abstract |
Receptor tyrosine kinase-like orphan receptor 1 (ROR1) is highly expressed in a wide variety of hematological and solid cancers, but is low or absent in adult tissues. Here, we show that ROR1 is released with exosomes from ROR1-positive cancer cells. We also developed a simple dissociation-enhanced lanthanide fluorescence immunoassay (DELFIA) to detect cancer-derived ROR1-positive exosomes, which are captured by two anti-ROR1 antibodies and detected by the fluorescence of free chelating europium. This new DELFIA method can detect cancer-derived ROR1-positive exosomes in the cell supernatant and serum with a wide range and rapidly compared with the conventional Western blot assay. This method may be useful as a companion diagnostics for ROR1-positive cancers.
