Chemical Information:

• Molecular Formula: C₁₆₄₀H₂₅₂₀N₄₂₈O₄₉₆ (approximate, glycoprotein-derived peptide fragment)
• Molecular Weight: ~38.7 kDa
• Sequence: Recombinant peptide fragment corresponding to the human follistatin 344 isoform

Molecular Structure:

Description:

Follistatin 344 is a recombinant peptide fragment derived from the human follistatin protein, a naturally occurring binding protein involved in activin and myostatin regulation. In laboratory research settings, follistatin-derived peptides are studied for their role in protein–protein binding, signaling modulation, and growth-regulatory pathways. Supplied as a lyophilized powder, Follistatin 344 is intended strictly for controlled in-vitro laboratory research and analytical applications. It is not designed for clinical, diagnostic, or therapeutic use.

Research Applications:

• Investigation of myostatin and activin binding dynamics
• In-vitro modeling of protein–protein interaction inhibition
• Studies involving cellular growth regulation and signaling pathways
• Research into developmental and regulatory protein interactions

Storage and Handling:

• Store lyophilized powder at −20 °C until use
• Once reconstituted, store at 2–8 °C and use promptly
• Avoid repeated freeze–thaw cycles
• Maintain aseptic laboratory technique during handling

Product Specifications:

• Purity: ≥99% (HPLC and Mass Spectrometry verified)
• Appearance: Lyophilized white to off-white powder
• Solubility: Soluble in mildly acidified aqueous solutions (e.g., acetic-acid–based laboratory buffers)

Compliance Notice:

Follistatin 344 is for research use only. Not approved for human or veterinary use. Not for diagnosis, treatment, cure, mitigation, or prevention of any disease. Buyer represents they are qualified to handle research materials and will use this product solely for lawful in-vitro research. Misuse, resale, or unauthorized application is strictly prohibited.
