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

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 (1958-GD), Recombinant Human BMP-6 (507-BP), and Recombinant Mouse BMP-6 (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 (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.

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.

  • Human/Mouse/Rat GDF-8/Myostatin Antibody
    Name: Sampath Kumar Anandan
    Application: Western Blot
    Sample Tested: Skeletal muscle tissue
    Species: Avian and Mouse
    Verified Customer | Posted 04/15/2024
    The test samples consisted of skeletal muscle tissue homogenates derived from mouse and avian muscle tissues. The homogenisation buffer contained protease inhibitor cocktail. The positive control used was 1μg of R&D systems recombinant myostatin/GDF8 (#788-G8). I had loaded 20μg of total protein for each of the avian and mouse samples, along with1μg of R&D systems recombinant myostatin/GDF8 (#788-G8) into a 4-15% gel. The electrophoresis was performed with MES running buffer at 90V constant current, and the proteins were subsequently blotted onto a 0.2μm nitrocellulose membrane. To check for transfer efficiency and protein integrity, i had stained the blot with Ponceau S and found that the transfer was efficient and the proteins were not degraded. Subsequently, i destained the blot with TBS-T and deionised water, and blocked the blots with 5% milk in TBS-T. Prior to incubating the membrane in primary antibody, i had cut the membrane such that one section contained all the animal tissue samples and the other section contained the recombinant GDF-8/myostatin and the western standard. The cut sections were incubated separately with identical concentrations of primary and secondary antibodies - R&D systems goat polyclonal GDF8 antibody (AF788-SP) at 2 µg/mL concentration, and R&D system anti-goat secondary antibody (HAF017) at 1:4000 dilution. The recombinant GDF-8/Myostatin positive control and the western standards produced clear and robust signals. However, the sections containing the samples derived from animal tissues (avian and mouse) failed to produce any discernible signal. I had repeated the same experiment above three times with increasing concentrations of primary antibody - 0.1, 0.25 and 2 µg/mL. However, all three experiments yielded the same result - strong signal for the recombinant GDF-8/Myostatin, but no visible signal detected with the avian and mouse tissue samples.
