Western blot analysis for expression of 5 RTKs in 4 HRS cell lines. Shown are Western blots of all 4 analyzed HRS cell lines for PDGFRA, DDR2, EPHB1, TRKA, and RON. All bands shown are of expected size. In the RON Western blot, the shorter band corresponds to the processed β-chain and the longer band to the unprocessed precursor.
