Contents Anti-GDF-8 mAb Form / storage Lyophilized or buffered protein; store −20 °C long-term / 4 °C short-term; avoid repeated freeze-thaw Purity ≥95% (SDS-PAGE) — see lot COA CAS N/A (monoclonal antibody) Molecular formula N/A — protein biologic (IgG1 class) Molecular weight ~145–150 kDa (typical intact IgG1) — confirm for the specific clone Sizes 1 mg Testing Identity & purity (SDS-PAGE), heavy metals, microbial COA Batch-specific — view on this page Research background This is a monoclonal antibody that binds growth differentiation factor-8 (myostatin), a TGF-β superfamily member that negatively regulates skeletal-muscle mass. Reagents in this class are designed to block myostatin’s interaction with activin type II receptors, interrupting its signaling in experimental systems. Myostatin-neutralizing antibodies are widely used in research on muscle-growth control, models of muscle wasting and dystrophy, and the TGF-β/SMAD signaling network. Spec note: “Antimyostatin antibody” is a class, not one defined molecule — confirm which specific clone Quantyx supplies, and adjust the purity line (antibodies are specified by SDS-PAGE / Protein A, not HPLC).
