Scientific Data Images for Rat FGF‑BP Antibody

FGF-BP antibody in Rat Thymus by Immunohistochemistry (IHC-Fr).

FGF-BP in Rat Thymus.

FGF-BP was detected in perfusion fixed frozen sections of rat thymus using Rat FGF-BP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1413) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific labeling was localized to the cytoplasm of lymphocytes. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

Applications for Rat FGF‑BP Antibody

Recommended Usage

Blockade of Receptor-ligand Interaction

In a functional ELISA, 0.5-2 µg/mL of this antibody will block 50% of the binding of 50 ng/mL of Recombinant Rat FGF-BP (Catalog # 1413-FB) to immobilized Recombinant Human FGF-basic (Catalog # 233-FB) coated at 5 µg/mL (100 µL/well). At 10 μg/mL, this antibody will block >90% of the binding.


5-15 µg/mL
Sample: Perfusion fixed frozen sections of rat thymus

Western Blot

0.1 µg/mL
Sample: Recombinant Rat FGF-BP (Catalog # 1413-FB)
Please Note: Optimal dilutions of this antibody should be experimentally determined.

Background: FGF-BP

Fibroblast growth factor binding protein (FGF-BP), also known as HBp17, is a secreted glycoprotein that increases the bioavailability of FGFs (1). Mature FGF-BP is a 34 kDa O-glycosylated protein with five conserved intrachain disulfide bonds (2-4). FGF-BP contains a heparin-binding domain (aa 113-146) and a distinct FGF-binding region (aa 197-238) (5). Mature rat FGF-BP shares 54% and 81% aa sequence identity with mouse and rat FGF-BP, respectively. FGF-BP is expressed throughout development and in adult squamous epithelium (6, 7). It is upregulated in injured skin, renal tubular epithelium, and spinal nerves as well as in carcinomas of the skin, colon, and pancreas (3, 8-11). FGF-BP binds FGF -1, -2, -7, -10, and -22 which are secreted and sequestered in the extracellular matrix (ECM) (8, 12). The interactions of FGF-BP with heparin sulfate proteoglycans (HSPG) and FGF, modulates their activities (7, 9 13, 14). FGF-BP enhances the mitogenic effects of FGFs, thereby contributing to epithelial, endothelial, and neuronal tissue repair, angiogenesis, and tumor growth (8-10, 12, 15, 16).
