Follistatin 344 1mg

OVERVIEW

Ultima-Follistion 344 1mg-int (R&D Only) is a high-purity, lyophilised research peptide derived from the 344-amino-acid isoform of naturally occurring human follistatin — a well-characterised regulatory glycoprotein. This product is manufactured under strict quality controls and is supplied exclusively for in vitro laboratory research, scientific study, and controlled R&D applications.

Follistatin-344 is one of the most extensively studied peptides in the field of protein-protein interaction research. Its documented ability to bind and neutralise members of the TGF-β (transforming growth factor-beta) superfamily — most notably myostatin and activin — makes it a valuable tool compound for researchers investigating cellular growth signalling, tissue differentiation, and metabolic regulatory pathways.

Whether you are a laboratory scientist, a research institution, or a qualified professional exploring the frontiers of peptide science, Ultima-Follistatin 344 1mg provides the purity, consistency, and documentation you need to conduct meaningful research with confidence.

RESEARCH BENEFITS & STUDIED APPLICATIONS

Follistatin-344 is studied across several areas of biochemical and molecular research. Documented areas of scientific investigation include:

Myostatin and Activin Pathway Modulation: FST-344 demonstrates high-affinity binding to myostatin and activin, two ligands within the TGF-β superfamily known to regulate muscle cell differentiation and growth signalling. This makes it a widely used tool compound in skeletal muscle research models.

Cellular Growth & Tissue Differentiation: Laboratory studies have explored follistatin’s role in stem cell maintenance, cell proliferation, and tissue repair mechanisms across multiple cell types and in vitro systems.

Reproductive and Endocrine Signalling: Follistatin isoforms are well-characterised in the context of reproductive biology and FSH regulation, making FST-344 relevant for studies in endocrine pathway research.

Inflammatory Pathway Modulation: Preclinical research has evaluated follistatin’s interaction with activin in inflammatory signalling cascades, offering potential utility in inflammation-focused research models.

Protein-Protein Interaction Studies: FST-344 is used extensively in assay environments designed to characterise binding kinetics and interaction dynamics between regulatory glycoproteins and their target ligands.

RECOMMENDED USAGE (RESEARCH PROTOCOL)

Ultima-Follistatin 344 1mg is intended exclusively for in vitro laboratory research by trained, qualified professionals in controlled research environments.

Reconstitution: Reconstitute with sterile, mildly acidic aqueous buffer (e.g., 0.1% acetic acid or appropriate laboratory buffer). Allow the peptide to dissolve gently — do not vortex aggressively.

Concentration: Prepare working concentrations appropriate to your specific assay design and experimental protocol. Typical in vitro concentrations vary by application; refer to published literature for guidance.

Handling: Use aseptic technique throughout. Avoid repeated freeze-thaw cycles — aliquot reconstituted solution as required for your experimental schedule.

Storage After Reconstitution: Store at 4°C for short-term use (up to 5–7 days). For longer storage, freeze at −20°C in single-use aliquots.

⚠ For in vitro research use only. Not for human or veterinary use. Not intended for diagnostic or therapeutic application. Handling must be conducted by qualified scientific professionals in an accredited research facility.
