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.

Detection of Mouse FGF-21 by Western Blot Increased cellular stress response in muscle of DTG mice.(A) Gene expression analysis of FGF21 in Quadriceps muscle by quantitative RT-PCR (n = 8 per group) and (B) FGF21 plasma concentration of 12-wk-old WT, DN-AMPK alpha 2, UCP1-TG and DTG mice (n = 9–10 per group). (B) Representative western blots of proteins involved in integrated stress response and FGF21 induction and (C) of cellular stress response markers HSP25 and HSP70 in Quadriceps muscle from 12-wk-old WT, DN-AMPK alpha 2, UCP1-TG and DTG mice, Mitofusin-2 (MFN2) was used as a loading control (n = 2 out of 6–8 analyzed per group). Means with different letters are significantly different (1way ANOVA and Bonferroni's multiple comparisons test, p<0.05).

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.
