| 目标/特异性 | Detects human KGF/FGF‑7 in direct ELISAs and Western blots. In direct ELISAs, approximately 50% cross-reactivity with recombinant mouse FGF-7 is observed, less than 20% cross-reactivity with recombinant human (rh) FGF-9 is observed, and less than 10% cross‑reactivity with rhFGF-4 and rhFGF-9 is observed. |
| 使用方法 | Western Blot: 0.1 µg/mL Immunohistochemistry: 5-15 µg/mL Neutralization: Measured by its ability to neutralize KGF/FGF‑7-induced proliferation in the 4MBr‑5 rhesus monkey epithelial cell line. The Neutralization Dose (ND50) is typically 6-12 µg/mL in the presence of 125 ng/mL Recombinant Human KGF/FGF‑7. |

| 背景 | KGF (keratinocyte growth factor), also known as FGF-7 (fibroblast growth factor-7), is one of 22 known members of the mouse FGF family of secreted proteins that plays a key role in development, morphogenesis, angiogenesis, wound healing, and tumorigenesis (1‑4). KGF expression is restricted to cells of mesenchymal origin. When secreted, it acts as a paracrine growth factor for nearby epithelial cells (1). KGF speeds wound healing by being dramatically upregulated in response to damage to skin or internal structures that results in high local concentrations of inflammatory mediators such as IL-1 and TNF-alpha. (2, 5). KGF promotes cell migration and invasion, and mediates melanocyte transfer to keratinocytes upon UVB radiation (6, 7). It has been used ectopically to avoid chemotherapy-induced oral mucositis in patients with hematological malignancies (1). Deletion of KGF affects kidney development, producing abnormally small ureteric buds and fewer nephrons (8). It also impedes hair follicle differentiation (9). The 194 amino acid (aa) KGF precursor contains a 31 aa signal sequence and, like all other FGFs, an ~120 aa beta -trefoil scaffold that includes receptor- and heparin-binding sites. KGF signals only through the IIIb splice form of the tyrosine kinase receptor, FGF R2 (FGF R2-IIIb/KGF R) (10). Receptor dimerization requires an octameric or larger heparin or heparin sulfate proteoglycan (11). FGF-10, also called KGF2, shares 51% aa identity and similar function to KGF, but shows more limited expression than KGF and uses an additional receptor, FGF R2-IIIc (12). Following receptor engagement, KGF is typically degraded, while FGF-10 is recycled (12). Mature human KGF, which is active across species, shares 98% aa sequence identity with bovine, equine, ovine and canine, 96% with mouse and porcine, and 92% with rat KGF, respectively. |

KGF/FGF‑7 in Human Placenta. KGF/FGF‑7 was detected in immersion fixed paraffin-embedded sections of human placenta (chorionic villi) using Goat Anti-Human KGF/FGF‑7 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-251-NA) at 10 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to trophoblast cells in chorionic villi. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections. | |
Cell Proliferation Induced by KGF/FGF‑7 and Neutralization by Human KGF/FGF‑7 Antibody. Recombinant Human KGF/FGF‑7 (Catalog # 251-KG) stimulates proliferation in the 4MBr‑5 rhesus monkey epithelial cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human KGF/FGF‑7 (125 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human KGF/FGF‑7 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-251-NA). The ND50 is typically 6-12 µg/mL. |
