Follistatin 344 1mg Peptides
Advance your experiments with a precisely characterized peptide standard designed for confident, repeatable results.
Follistatin 344 from Peptide Scientific Labs is supplied as a peptide lyophilized vial (powder format) for laboratory reconstitution. This growth factor–related peptide is presented at 1mg total content to support standardized in vitro workflows, assay development, and reproducible method optimization.
- Each vial contains 1mg of Follistatin 344, a binding protein–derived peptide widely investigated for its role within the activin/myostatin axis and broader growth factor signaling—suited to studies of receptor engagement, cellular pathways, and assay calibration.
Developed for non-clinical research, this neutral, unflavored lyophilized format enables flexible buffer selection and protocol-specific concentrations without unnecessary additives. Researchers value its dependable lot-to-lot consistency, clean reconstitution characteristics, and stable performance in diverse experimental designs—including dose–response curves, pathway mapping, receptor-binding investigations, and preclinical screening environments where data clarity is essential.
The experience is engineered around reliability: a carefully handled, sealed vial that integrates smoothly into standard laboratory workflows. Its format supports controlled method building, facilitating consistent aliquoting and minimizing variability during preparation. Whether used as a primary test article or as a reference material alongside complementary analytes, Follistatin 344 is positioned to help laboratories generate coherent, comparable results across iterative studies.
Every lot is produced under stringent quality controls in the United States and evaluated for identity and purity by high-performance liquid chromatography and mass spectrometry. A lot-specific Certificate of Analysis provides clear documentation of testing outcomes, supporting internal review, recordkeeping, and compliance needs. Vials are handled with environmental controls and secured in tamper-evident packaging to protect sample integrity during shipment and storage. Peptide Scientific Labs emphasizes accuracy in specifications, consistency in manufacturing, and transparent reporting—foundation elements for research teams focused on sound, defensible data.

Frequently Asked Questions
What are growth factors?
Growth factors are a class of signaling proteins and peptides that regulate cell proliferation, differentiation, and survival. Well-studied examples include insulin-like growth factor 1 (IGF-1), fibroblast growth factors (FGFs), epidermal growth factor (EGF), platelet-derived growth factor (PDGF), and nerve growth factor (NGF).
In research, growth factors are essential tools for cell culture, regenerative biology, developmental studies, and cancer research. They are typically used at low concentrations to stimulate specific cellular responses in vitro. All growth factor products from Peptide Scientific Labs are intended for laboratory research use only.
What is the role of IGF-1 in research?
Insulin-like growth factor 1 (IGF-1) is a 70-amino-acid peptide with significant structural similarity to insulin. It is one of the most-studied growth factors in research and is a central player in studies of cell proliferation, differentiation, metabolism, and tissue growth. IGF-1 acts through its own receptor (IGF-1R), which shares downstream signaling components with the insulin receptor.
In the laboratory, IGF-1 is used as a reference ligand in receptor-binding studies, as a supplement in cell culture media for certain cell lines, and as a model peptide in studies of the PI3K/AKT/mTOR signaling pathway. IGF-1 products from Peptide Scientific Labs are supplied for these kinds of research applications only.
How do growth factors differ from peptide hormones?
Peptide hormones — such as insulin, glucagon, and growth hormone — are typically produced by specialized endocrine glands and act on distant target tissues as part of systemic regulation. Growth factors are usually produced by a wider variety of cell types and tend to act in a more local manner, through autocrine or paracrine signaling on nearby cells.
Another difference lies in their biological roles: peptide hormones are generally studied in the context of metabolic and endocrine regulation, while growth factors are more commonly studied in the context of development, tissue repair, and proliferation. In practice, the categories overlap, especially for molecules like IGF-1 that behave in both ways.
