Mouse FGF-21 Antibody Summary

Species Reactivity
Detects mouse FGF-21 in direct ELISAs and Western blots. In these formats, approximately 15% cross‑reactivity with recombinant human (rh) FGF-21 is observed and less than 1% cross-reactivity with rhFGF-19 and rhFGF-23 is observed.
Polyclonal Goat IgG
Antigen Affinity-purified
E. coli-derived recombinant mouse FGF-21
Accession # Q9JJN1
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
<0.10 EU per 1 μg of the antibody by the LAL method.


Recommended Concentration
Western Blot
0.25 µg/mL

Data Example

Western Blot Detection of Mouse FGF-21 antibody by Western Blot. View Larger

Detection of Mouse FGF‑21 by Western Blot. Western blot shows lysates of mouse spleen tissue and rat spleen tissue. PVDF membrane was probed with 0.25 µg/mL of Goat Anti-Mouse FGF-21 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3057) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for FGF-21 at approximately 26 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: FGF-21

Mouse FGF-21 is a 20 kDa, secreted, nonglycosylated polypeptide that is a member of the FGF family. It is synthesized as a 210 amino acid (aa) precursor that contains a 28 aa signal sequence and a 182 aa mature region. Mature mouse FGF-21 shares 81%, 80%, 79% and 92% aa sequence identity with human, bovine, canine and rat FGF-21, respectively. FGF-21 seems to be produced by the liver and exhibits unique antidiabetogenic effects in fat.
