Product Overview

Follistatin 344 is a naturally derived isoform of the follistatin glycoprotein family, consisting of 344 amino acid residues. It is one of the most extensively studied activin-binding proteins in molecular biology and endocrinology research. Follistatin 344 functions primarily as an antagonist of activin and certain members of the TGF-β superfamily, making it a subject of significant interest across a range of in vitro and preclinical research disciplines. Revo Peptide’s bulk 50-vial offering is purpose-built for research institutions, academic laboratories, and contract research organizations seeking consistent, high-purity supply at a competitive price point.

Peptide Structure & Amino Acid Sequence

Follistatin 344 is a 344-residue isoform produced via alternative splicing of the follistatin gene. Its structure includes three follistatin domain (FSD) repeats, an N-terminal domain (ND), and a heparan sulfate proteoglycan (HSPG) binding region at the C-terminus. This C-terminal extension distinguishes FST344 from the shorter FST288 isoform and confers distinct cell-surface binding properties relevant to extracellular matrix interaction studies. The protein is produced through chemical synthesis and is presented in lyophilized form to preserve structural integrity during storage and shipping.

Chemical & Physical Characteristics

• Appearance: White lyophilized powder
• Molecular Weight: Approximately 35–37 kDa (glycosylated form varies)
• Solubility: Soluble in sterile water or 1% acetic acid
• Source: Chemical synthesis
• Unit Size: 1 mg per vial
• Isoform: Follistatin 344 (FST344)

The lyophilized white powder format ensures maximum shelf stability and minimizes degradation risk during transit, making it the preferred presentation for bulk research procurement.

Purity & Analytical Verification (HPLC & MS)

Every production batch of Follistatin 344 supplied by Revo Peptide undergoes rigorous analytical testing prior to release. Purity is confirmed at ≥98% via reverse-phase high-performance liquid chromatography (RP-HPLC). Identity is further validated through mass spectrometry (MS), confirming correct molecular weight and sequence fidelity. Certificates of Analysis (CoA) are available upon request and accompany all bulk orders to ensure full traceability and documentation for institutional compliance purposes.

Quality Control & Lyophilization Integrity

Revo Peptide employs pharmaceutical-grade lyophilization protocols to ensure that each vial retains full structural integrity from production through delivery. The lyophilization process removes residual moisture to levels below 5%, preventing hydrolytic degradation and microbial contamination during storage. Each vial is sealed under inert atmosphere conditions and undergoes visual inspection and weight verification as part of our standard quality control pipeline. Bulk orders are batch-coded to allow full lot traceability.

Safety, Handling & Laboratory Precautions

Follistatin 344 is intended exclusively for qualified researchers working in properly equipped laboratory environments. Standard laboratory safety practices must be observed at all times. Personnel handling this compound should wear appropriate personal protective equipment (PPE), including gloves, lab coat, and eye protection. This product has not been evaluated for safety in biological systems and must not be administered to humans or animals under any circumstances. Disposal must comply with applicable institutional and regulatory waste management protocols.

Reconstitution, Packaging & Storage

• Reconstitution: Dissolve in sterile water or 1% acetic acid for in vitro laboratory use only
• Room Temperature Stability: Lyophilized Follistatin 344 is stable at room temperature for up to 90 days
• Long-Term Storage: Store below -8°C in a freezer for extended periods
• Packaging: 50 individually sealed vials, 1 mg per vial, presented in a secure bulk packaging format
• Avoid: Repeated freeze-thaw cycles; aliquot upon reconstitution where possible

Revo Peptide recommends storing all peptide vials in a dedicated -20°C or lower freezer and maintaining a cold chain during transit. Bulk orders ship with appropriate cold-pack insulation to preserve product integrity.
