Fibroblast growth factor-9 (FGF-9) is a steroid-regulated mitogen and survival factor for nerve and mesenchymal cells. The human FGF-9 cDNA cloned by using oligonucleotide probes encodes a polypeptide consisting of 208 amino acids. Sequence similarity to other members of the FGF family has been estimated to be around 30%. FGF-9 is an autocrine estromedin endometrial stromal growth factor that plays roles in cyclic proliferation of uterine endometrial stroma. FGF-9 is produced and secreted by the prostatic stromal cells. It is a potent mitogen for both prostatic epithelial and stromal cells in culture. FGF-9 is an abundant secreted growth factor that can act as both a paracrine mitogen for epithelial cells and an autocrine mitogen for stromal cells. Overexpression of FGF-9 may play an important role in the epithelial and stromal proliferation in benign prostatic hyperplasia. The standard product used in this kit is recombinant human FGF-9, consisting of 208 amino acids with the molecular mass of 23KDa. As a result of glycosylation, the molecular mass is 25-27KDa.
ScienCell's human FGF-9 ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. Human FGF-9-specific monoclonal antibodies are pre-coated onto 8 x 12 divisible strips. The human specific detection polyclonal antibodies are biotinylated. The test samples and biotinylated detection antibodies are subsequently added to the wells and then washed with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. HRP substrate TMB is used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes into yellow after adding acidic stop solution. The intensity of yellow is proportional to the amount of human FGF-9 captured in strips.
