Follistatin 344 is a synthetic peptide with a molecular weight of ~37,000 g/mol and molecular formula Recombinant protein. Supplied as a lyophilised solid, each batch is verified to ≥95% purity via HPLC analysis and accompanied by a Certificate of Analysis (COA).
Follistatin 344 is reconstitute in sterile water or pbs. For optimal stability, store the unopened vial at -80 °C preferred; -20 °C acceptable. Stable for up to 7 days at 2–8 °C; aliquot to avoid repeated freeze-thaw.
Every compound we supply is synthesized in ISO-certified GMP facilities using automated solid-phase peptide synthesis, ensuring batch-to-batch consistency and accurate sequencing.
Each batch undergoes independent third-party testing — HPLC for purity verification (≥97%), mass spectrometry for identity confirmation, and endotoxin screening (<1 EU/μg). A full Certificate of Analysis ships with every order.
We offer free worldwide shipping with temperature-controlled packaging, anonymous checkout for your privacy, and responsive support from a team that understands research-grade compounds.
