Follistatin 344 (1mg)

Description

• Composition and format
Follistatin 344 (1 mg) is a recombinant peptide supplied as a lyophilized powder in a single vial. Each vial contains 1 mg of Follistatin 344. The batch-specific Certificate of Analysis (COA) provides protein sequence confirmation, molecular weight verification, and formulation details to support method-level reproducibility and documentation control in research environments.
 

• Analytical verification
Each lot is qualified at 95%+ purity by high-performance liquid chromatography; protein identity and structural integrity are confirmed by mass spectrometry. Independent third-party laboratories corroborate in-house analytical results to maintain traceable quality metrics appropriate for research use.
• Intended research use
Follistatin 344 is evaluated exclusively in controlled in-vitro systems investigating activin-binding interactions, growth factor signaling pathways, and cellular differentiation models under defined assay conditions. All technical communications are method-centric and do not imply diagnostic, therapeutic, performance, or clinical outcomes in humans or animals.
 

• Research characteristics and applications
Follistatin 344 is characterized by a defined protein structure with high affinity for members of the transforming growth factor-beta (TGF-β) superfamily. In controlled in-vitro environments, researchers employ Follistatin 344 to study ligand-binding dynamics, signaling pathway modulation, and regulatory interactions involving activins and related proteins. Representative applications include assay development, mechanistic pathway investigations, concentration-response analyses, and cellular signaling characterization strictly within laboratory settings.
