Figure 1From: Targeting both IGF-1R and mTOR synergistically inhibits growth of renal cell carcinoma in vitro Characterization of Hex-hR1 and 1R-2b. A 50-μg sample of (A) Hex-hR1 or (B) 1R-2b was run on SE-HPLC as described in Materials and Methods. Histograms show UV absorbance of eluted material versus time. (C) Cell binding of hR1, Hex-hR1, and 1R-2b at equimolar concentrations on ACHN cells by FACS staining. Anti-CD20 antibody, hA20, served as negative control.Back to article page
