Bovine FGF acidic/FGF1 Antibody Summary

Species Reactivity
Detects bovine FGF acidic/FGF1 in direct ELISAs and Western blots. In direct ELISAs and Western blots, this antibody will recognize both bovine FGF acidic/FGF1 and recombinant human (rh) FGF acidic/FGF1. In direct ELISAs, no cross‑reactivity with rhFGF-basic, rhFGF-4, -5, -6, -7 or -9 is observed. Neutralizes the biological activity of bovine FGF acidic/FGF1 and will also neutralize the biological activity of rhFGF acidic/FGF1, although 5 times the amount of IgG is required.
Polyclonal Rabbit IgG
Protein A or G purified
Bovine brain-derived FGF acidic/FGF1
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.


Recommended Concentration
Western Blot
1 µg/mL
Bovine FGF acidic/FGF1 (Catalog # 132-FA)
Measured by its ability to neutralize FGF acidic/FGF1-induced proliferation in the NR6R‑3T3 mouse fibroblast cell line. The Neutralization Dose (ND50) is typically 1-3 µg/mL in the presence of 0.75 ng/mL Bovine FGF acidic/FGF1.

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 FGF acidic/FGF1 and Neutral-ization by Bovine FGF acidic/FGF1 Antibody. Bovine FGF acidic/FGF1 (Catalog # 132-FA) stimulates proliferation in the NR6R-3T3 mouse fibroblast cell line in a dose-dependent manner (orange line). Proliferation elicited by Bovine FGF acidic/FGF1 (0.75 ng/mL) is neutralized (green line) by increasing concentrations of Rabbit Anti-Bovine FGF acidic/FGF1 Polyclonal Antibody (Catalog # AB-32-NA). The ND50 is typically 1-3 µg/mL.

Background: FGF acidic/FGF1

FGF acidic, also known as FGF1, ECGF, and HBGF-1, is a 17 kDa nonglycosylated member of the FGF family of mitogenic peptides. FGF acidic, which is produced by multiple cell types, stimulates the proliferation of all cells of mesodermal origin and many cells of neuroectodermal, ectodermal, and endodermal origin. It plays a number of roles in development, regeneration, and angiogenesis (1‑3). Bovine FGF acidic shares 53% amino acid sequence identity with FGF basic and 11%‑31% with other bovine FGFs. It shares 92%, 91%, 88%, and 91% aa sequence identity with human, mouse, porcine, and rat FGF acidic, respectively, and exhibits considerable species crossreactivity. During its nonclassical secretion, FGF acidic associates with S100A13, copper ions, and the C2A domain of synaptotagmin 1 (4). It is released extracellularly as a disulfide-linked homodimer and is stored in complex with extracellular heparan sulfate (5). The ability of heparan sulfate to bind FGF acidic is determined by its pattern of sulfation, and alterations in this pattern during embryognesis thereby regulate FGF acidic bioactivity (6). The association of FGF acidic with heparan sulfate is a prerequisite for its subsequent interaction with FGF receptors (7, 8). Ligation triggers receptor dimerization, transphosphorylation, and internalization of receptor/FGF complexes (9). Internalized FGF acidic can translocate to the cytosol with the assistance of Hsp90 and then migrate to the nucleus by means of its two nuclear localization signals (10‑12). The phosphorylation of FGF acidic by nuclear PKC delta triggers its active export to the cytosol where it is dephosphorylated and degraded (13, 14). Intracellular FGF acidic functions as a survival factor by inhibiting p53 activity and proapoptotic signaling (15).
