Western Blot Detection of Recombinant Human, Mouse, and Rat GDF-8/Myostatin antibody by Western Blot. View Larger

Detection of Recombinant Human, Mouse, and Rat GDF-8/Myostatin by Western Blot. Western blot shows 25 ng of Recombinant Human/Mouse/Rat GDF-8/Myostatin (788-G8), Recombinant Human/Mouse/Rat GDF-11/BMP-11 (Catalog # 1958-GD), Recombinant Human BMP-6 (507-BP), and Recombinant Mouse BMP-6 (Catalog # 6325-BM). PVDF Membrane was probed with 0.1 µg/mL of Goat Anti-Human/Mouse/Rat GDF-8/Myostatin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF788) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for GDF-8/Myostatin at approximately 14 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.

GDF‑8/Myostatin in Mouse Embryo. GDF-8/Myostatin was detected in immersion fixed frozen sections of mouse embryo (10 d.p.c., section through neural tube) using Goat Anti-Human/Mouse/Rat GDF-8/Myostatin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF788) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; CTS008) and counterstained with hematoxylin (blue).

Neutralization Hemoglobin Expression Induced by GDF‑8/Myostatin and Neutralization by Mouse GDF‑8/Myostatin Antibody. View Larger

Hemoglobin Expression Induced by GDF‑8/Myostatin and Neutralization by Mouse GDF‑8/Myostatin Antibody. Recombinant Mouse GDF-8/Myostatin (Catalog # 788-G8) increases hemoglobin expression in the K562 human chronic myelogenous leukemia cell line in a dose-dependent manner (orange line), as measured by the psuedoperoxidase assay. Hemoglobin expression elicited by Recombinant Mouse GDF-8/Myostatin (30 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human/Mouse/Rat GDF-8/Myostatin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF788). The ND50 is typically 0.6-3 µg/mL.

Background: GDF-8/Myostatin

Growth Differentiation Factor 8 (GDF-8), also known as myostatin, is a member of the TGF-beta superfamily that is expressed specifically in developing and adult skeletal muscle. GDF-8 cDNA encodes a 376 amino acid (aa) prepropeptide with a 24 aa residue signal peptide, a 223 aa residue amino-terminal propeptide, and a 109 aa residue carboxy-terminal mature protein. Mature GDF-8 contains the canonical 7-cysteine motif common to other TGF-beta superfamily members. Similar to the TGF-beta s, activins and BMP-11, GDF-8 also contains one extra pair of cysteine residues that is not found in other family members. The bioactive form of GDF-8 is a homodimer with an apparent molecular weight of approximately 25 kDa. GDF-8 is highly conserved across species. At the amino acid sequence level, mature human, mouse, rat and cow GDF-8 are 100% identical. Within the TGF-beta superfamily, GDF-8 is most closely related to BMP-11, a mammalian protein that acts as a dorsal mesoderm and neural inducer in Xenopus explants. The two proteins share 90% amino acid sequence identity within their mature chain. A targeted disruption of GDF-8 in mouse results in large mice with a widespread increase in skeletal muscle mass, indicating that GDF-8 is a negative regulator of skeletal muscle growth. A mutation in the bovine GDF-8 gene has been shown to be responsible for the double-muscled phenotype in cattle breeds such as Belgian Blue cattle that is characterized by an increase in muscle mass. GDF-8 has also been shown to inhibit preadipocyte differentiation to adipocytes. Mature GDF-8 binds to activin type II receptors and the binding is antagonized by the activin-binding protein, follistatin. R&D Systems recombinant GDF-8 preparations have been shown to act similarly to Activin A in both the Xenopus animal cap and the K562 assays.
