Less than 1.0 EU/ug as determined by LAL method.
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Myostatin is a negative regulator of skeletal muscle mass, making it a critical target for understanding muscle wasting, cachexia, and regenerative pathways. This full-length human protein (aa 24–375) demonstrates specific receptor engagement, binding human ACVR2B with an EC50 of 68.26–74.59 ng/mL in functional ELISA, a potency range that supports receptor-ligand competition assays and antibody characterization studies where quantitative binding kinetics are essential. Mammalian expression preserves native post-translational modifications, aligning with standards expected in cell-based differentiation models and in vivo muscle biology experiments. Purity exceeding 95% by SDS-PAGE and endotoxin below 1.0 EU/μg meet the quality thresholds commonly required for stem cell differentiation assays and primary myoblast culture systems, where contaminants can confound proliferation and myogenic commitment readouts.
