The family of fibroblast growth factor receptors (FGFRs) plays an important role in cell growth, survival, differentiation and angiogenesis. The three immunoglobulin-like extracellular domains of FGFR (D1, D2, and D3) are critical for ligand binding and specificity towards fibroblast growth factor and heparan sulfate. Fibroblast growth factor receptors are overexpressed in a wide variety of tumors, such as breast, bladder, and prostate cancer, and therefore they are attractive targets for different types of anticancer therapies. In this study, we have cloned, expressed in CHO cells and purified Fc-fused extracellular domains of different types of FGFRs (ECD_FGFR1a-Fc, ECD_FGFR1b-Fc, ECD_FGFR2a-Fc, ECD_FGFR2b-Fc, ECD_FGFR3a-Fc, ECD_FGFR3b-Fc, ECD_FGFR4a-Fc, ECD_FGFR4b-Fc), which could be used as molecular targets for the selection of specific antibodies. The fusion proteins were analyzed using gel electrophoresis, Western blotting and mass spectrometry. To facilitate their full characterization, the fusion proteins were deglycosylated using PNGase F enzyme. With an optimized transient transfection protocol and purification procedure we were able to express the proteins at a high level and purify them to homogeneity.
