Generation and characterization of a panel of monoclonal antibodies specific for human fibroblast growth factor receptor 4 ( FGFR4).

Fibroblast growth factor receptor 4 ( FGFR4) is a member of the FGFR family of receptor tyrosine kinases, and plays important roles in a variety of biological functions such as cell proliferation, differentiation, migration, angiogenesis, tissue repair, and tumorigenesis. The human FGFRs share a high degree of sequence homology between themselves, as well as with their murine homologs. Consequently, it has been suggested that it may be difficult to prepare monoclonal antibodies (MAbs) that are specific for the individual receptor types. In this communication, we report on the development and characterization of a panel of anti-human FGFR4 MAbs that were generated in mice using a rapid immunization protocol. Using a modified rapid immunization at multiple sites (RIMMS) protocol with the soluble extracellular domain of human FGFR4 ( FGFR4- ECD), the immunized mice developed high levels of polyclonal IgG to the immunogen within 13 days of the first immunization. The lymph node cells isolated from the immunized animals were then fused with mouse myeloma cells for hybridoma generation. Use of an efficient hybridoma cloning protocol in combination with an ELISA screening procedure allowed for early identification of stable hybridomas secreting antihuman FGFR4 IgG. Several identified MAbs specifically reacted with the FGFR4 protein without binding to the other human isoforms (FGFR1, FGFR2, and FGFR3). As evaluated by BIAcore analysis, most anti- FGFR4 MAbs displayed high affinities (8.6 x 10(8) approximately 3.9 x 10(10) M) to FGFR4. Furthermore, these MAbs were able to bind to FGFR4 expressed on human breast tumor cell lines MDA-MB-361 and MDA-MB-453. Taken together, the results demonstrate that the RIMMS strategy is an effective approach for generating class-switched, high-affinity MAbs in mice to evolutionarily conserved proteins such as human FGFR4. These MAbs may be useful tools for further investigation of the biological functions and pathological roles of human FGFR4.[1]
