Product Overview

Follistatin 315 is biochemically classified as the primary circulating isoform of the autocrine glycoprotein follistatin family. It is a naturally occurring peptide analogue that has been synthetically reproduced for use as a laboratory research tool in the study of musculoskeletal development, cellular longevity tracking, and metabolic regulation. Functioning as a potent non-competitive antagonist, Follistatin 315 plays a foundational role in investigating the biological mitigation of degenerative muscle wasting and age-associated systemic decline. Researchers and institutions looking to buy Follistatin 315 online will find The Peptide Store’s 1mg configuration ideal for precise, reproducible in vitro and ex vivo study designs.

Peptide Structure & Amino Acid Sequence

Follistatin 315 is distinguished from other isoforms — most notably Follistatin 344 — by a specific C-terminal acidic tail modification that enables systemic circulation and effective peripheral tissue targeting. While Follistatin 344 exhibits predominantly localized, autocrine-dominant activity, the 315 isoform’s structural configuration allows it to engage peripheral tissues beyond the immediate site of expression. This isoform-specific structural feature makes Follistatin 315 a uniquely valuable research tool for studying endocrine-like distribution mechanisms and multi-tissue signaling dynamics in controlled laboratory environments.

Chemical & Physical Characteristics

Follistatin 315 is a glycoprotein-class synthetic peptide with a molecular architecture that includes multiple follistatin domain repeats responsible for its ligand-binding activity. In its lyophilized form, the compound presents as a white to off-white powder. It is water-soluble and exhibits stability under appropriate cold-chain storage conditions. The compound’s physicochemical profile supports its utility across a range of biochemical assay formats, including binding affinity studies, receptor interaction profiling, and pathway modulation experiments.

Purity & Analytical Verification (HPLC & MS)

Every batch of Follistatin 315 1mg available for sale at The Peptide Store is independently verified to a minimum purity of ≥98% using high-performance liquid chromatography (HPLC). Mass spectrometry (MS) analysis is additionally employed to confirm correct molecular identity and structural integrity. These dual-verification methods ensure that each unit dispatched meets the rigorous analytical standards demanded by academic, pharmaceutical, and biotechnology research teams. Certificates of Analysis (CoA) are available upon request to support full traceability and reproducibility of research outcomes.

Quality Control & Lyophilization Integrity

Follistatin 315 is produced under tightly controlled manufacturing conditions and subjected to multi-stage quality control protocols prior to lyophilization. The lyophilization process removes residual moisture to extend shelf life and preserve structural integrity during transit and storage. Each vial is sealed under inert conditions to prevent oxidative degradation. The Peptide Store’s commitment to consistent batch quality means researchers can rely on product-to-product reproducibility — a critical factor when designing longitudinal or comparative studies.

Safety, Handling & Laboratory Precautions

Follistatin 315 1mg is intended exclusively for use by qualified researchers in properly equipped laboratory settings. Standard laboratory personal protective equipment (PPE) — including gloves, eye protection, and appropriate laboratory attire — should be worn at all times when handling this compound. Researchers should consult relevant institutional biosafety protocols before initiating work with this material. This product is not approved for administration to humans or animals under any circumstances.

Reconstitution, Packaging & Storage

Follistatin 315 1mg is supplied in a sealed, sterile vial in lyophilized powder form. For optimal stability, the lyophilized product should be stored at -20°C or below, protected from light and moisture. All reconstitution procedures must be conducted strictly in accordance with institutional laboratory protocols and are intended solely for in vitro or ex vivo research applications. Once reconstituted, solutions should be aliquoted promptly and stored appropriately to minimize freeze-thaw degradation cycles.

Intended Research Use & Market Positioning

Follistatin 315 is positioned as a leading research-grade compound for scientists investigating myostatin inhibition, activin signaling, skeletal muscle biology, and tissue growth regulation. Its systemic circulation profile makes it particularly relevant for studies examining multi-tissue effects of TGF-β superfamily antagonism. Research teams in the fields of endocrinology, sports science biology, aging research, and regenerative medicine modeling will find this compound to be a well-characterized and analytically verified tool.
