Human KGF/FGF-7 Antibody Summary

Species Reactivity

Human

Specificity

Detects human KGF/FGF‑7 in direct ELISAs. In direct ELISAs, no cross-reactivity with recombinant human (rh) FGF-3, rhFGF-4, rhFGF-5, rhFGF-6, rhFGF acidic, or rhFGF basic is observed.

Source

Monoclonal Mouse IgG₁ Clone # 29522

Purification

Protein A or G purified from ascites

Immunogen

E. coli-derived recombinant human KGF/FGF‑7
Cys32-Thr194
Accession # P21781

Formulation

Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Endotoxin Level

Applications

Recommended Concentration

Sample

Human KGF/FGF-7 Sandwich Immunoassay

Recommended Concentration

Reagent

ELISA Capture (Matched Antibody Pair)

2-8 µg/mL

Use in combination with:

Detection Reagent: Human KGF/FGF‑7 Biotinylated Antibody (Catalog # BAF251)

Standard: Recombinant Human KGF/FGF-7 Protein (Catalog # 251-KG)

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 0.1-0.5 µg/mL in the presence of 100 ng/mL Recombinant Human KGF/FGF‑7.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

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), as measured by Resazurin (Catalog # AR002). Proliferation elicited by Recombinant Human KGF/FGF-7 (100 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human KGF/FGF-7 Monoclonal Antibody (Catalog # MAB251). The ND₅₀ is typically 0.1-0.5 µg/mL.

Background: KGF/FGF-7

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.
