| Fibroblast growth factor 7 (FGF7) is a member of the fibroblast growth factor (FGF) family of proteins. FGF7 is of stromal origin and produces a paracrine effect on epithelial cells. In the current investigation, we aimed to identify new singledomain antibodies (sdAbs) against FGF7 using phage display technology. The vector harboring the codon-optimized DNA sequence for FGF7 protein was transformed into Escherichia coli BL21 (DE3) pLysS, and then the protein was expressed at the optimized condition. Enzyme-linked immunosorbent assay, circular dichroism spectropolarimetry, and in vitro scratch assay experiments were used to confirm the proper folding and functionality of the purified FGF7 protein. The purity of the produced FGF7 was 92%, with production yield of 3.5 mg/L of culture. Panning against the purified FGF7 was performed, and the identified single-domain antibodies showed significant affinity. Further investigation on one of the selected sdAb displaying phage clones showed concentration-dependent binding to FGF7. The selected sdAb can be used for developing novel tumor-suppressing agents where inhibition of FGF7 is required. |
