  • Synonym
    GDF-8, Myostatin, GDF8, MSTN, Growth, differentiation factor 8
  • Source
    Biotinylated Cynomolgus latent GDF-8 Protein, Avitag,His Tag(GD8-C82Q3) is expressed from human 293 cells (HEK293). It contains AA Gly 19 - Ser 375 (Accession # Q95J86).
    Predicted N-terminus: Gly
  • Molecular Characterization
    GDF-8 Structure

    This protein carries an Avi tag (Avitag™) at the N-terminus, followed by a polyhistidine tag.

    The protein has a calculated MW of 44.1 kDa. The protein migrates as 11-12 kDa, 40-43 kDa and 55 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Labeling
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Protein Ratio
    Passed as determined by the HABA assay / binding ELISA.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method / rFC method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

  • Background
    Growth differentiation factor 8 (GDF8), also known as myostatin, is a unique member of the transforming growth factor-β superfamily that is expressed in human granulosa cells and has important roles in regulating a variety of ovarian functions. GDF8 acts as a negative regulator of skeletal muscle growth and differentiation. In addition to the expression in the musculoskeletal system, GDF8 is also expressed in various tissues, including the reproductive system.
