Follistatin 344 – 1MG (98% purity)

Permagainz Follistatin 344 is a recombinant research peptide supplied for in-vitro and laboratory use only. It represents the 344-amino-acid isoform of the naturally occurring follistatin protein, a member of the activin-binding glycoprotein family. Researchers employ Follistatin 344 to investigate myostatin inhibition, TGF-β signalling, and muscle-cell differentiation pathways under controlled experimental conditions.

Each vial contains 1 mg of lyophilised Follistatin 344, produced under ISO-certified laboratory conditions to guarantee accuracy, purity, and reproducibility.

Chemical Background / Research Profile

Follistatin 344 has a molecular weight of approximately 38.2 kDa and binds activin A, B, and myostatin in cell-culture models. In laboratory research, it is used to:

• Examine ligand–receptor interactions within the TGF-β superfamily.

• Study regulation of myogenic growth factors in cultured myoblasts.

• Explore signal transduction and transcriptional control of growth-related genes.

By neutralising activin and myostatin signalling in vitro, Follistatin 344 serves as a valuable model for understanding cellular feedback mechanisms, protein–protein interactions, and growth regulation pathways without any biological administration to humans or animals.

Purity and Quality Assurance

All Permagainz peptides are manufactured to ≥ 98 % purity, confirmed by HPLC and mass spectrometry (MS).
Production follows Good Manufacturing Practice (GMP) and Good Laboratory Practice (GLP) guidelines within ISO-accredited clean-room facilities.

Each vial is sealed under sterile conditions and supplied with a Certificate of Analysis (CoA) verifying identity, purity, batch number, and expiry date for full traceability.

Laboratory Handling and Storage

• Store at 2–8 °C, away from light and moisture.

• For extended storage, freeze at –20 °C.

• Allow to reach ambient temperature before opening to prevent condensation.

• Reconstitute using sterile bacteriostatic water or equivalent laboratory-grade solvent under aseptic conditions.

• Avoid repeated freeze–thaw cycles; discard remaining material according to institutional biosafety procedures.

Personnel must handle all peptide materials wearing suitable PPE (gloves, laboratory coat, eye protection) within approved research environments.

Safety, Compliance and Restrictions

Follistatin 344 is supplied strictly for laboratory research use only. It is not a medicinal product, not for human or veterinary consumption, and not approved for diagnostic, therapeutic, or cosmetic application.

Permagainz operates in full accordance with MHRA, REACH, and COSHH safety frameworks governing the distribution of research-only chemical materials.

Through meticulous quality control and transparent documentation, Permagainz ensures Follistatin 344 – 1 mg meets the highest standards for legitimate scientific investigation into peptide biology and molecular signalling.
