Follistatin 315 (1mg) is a recombinant protein supplied exclusively for controlled in-vitro laboratory research. It is commonly evaluated in experimental systems involving activin-class ligands, myostatin-related signaling, and transforming growth factor beta (TGF-β) superfamily pathways.
Follistatin 315 may be used in ligand-binding assays, protein-interaction studies, analytical characterization, and other controlled laboratory investigations. Experimental results depend on the selected assay, test system, controls, and laboratory conditions. No diagnostic, therapeutic, or clinical use is intended or authorized.
Nordsci Peptides provides lot-specific analytical documentation for applicable products. Researchers should review the Certificate of Analysis before beginning an experiment and independently determine whether the material is appropriate for the intended laboratory protocol.
The primary concern for peptide researchers today is product purity. Nord-sci guarantees our product purity by performing independent testing of our products and providing those certifications for our customers in our product descriptions.
THIS PRODUCT IS NOT INTENDED TO TREAT, CURE OR DIAGNOSE ANY CONDITION OR DISEASE AND IS NOT FOR HUMAN CONSUMPTION. ALL PRODUCTS OFFERED ARE INTENDED FOR LABORATORY RESEARCH USE ONLY.
All products are produced using lyophilization (freeze-drying), a preservation method that allows peptides to remain fully stable during shipping for approximately 3-4 months. Once a peptide has been reconstituted with bacteriostatic water, it must be refrigerated to maintain integrity. After reconstitution, peptides typically remain stable for up to 30 days when stored properly.
Lyophilization, also referred to as cryodesiccation, is a specialized dehydration process in which peptides are first frozen and then exposed to a low-pressure environment. This causes the water within the vial to transition directly from a solid to a vapor (sublimation), leaving behind a dry, crystalline white material known as a lyophilized peptide. In this powdered form, peptides may be safely stored at room temperature until they are ready to be reconstituted with bacteriostatic water.
After delivery, peptides should be protected from heat and light. If use is expected within the near future (whether days, weeks, or a few months) refrigerated storage below 4°C (39°F) is generally sufficient. Lyophilized peptides are commonly stable at room temperature for several weeks or longer, making short-term ambient storage acceptable when use is anticipated within that timeframe.
For extended storage, ranging from several months to multiple years, freezing is strongly recommended. Storage at -80°C (-112°F) offers optimal long-term stability and helps preserve peptide structure and quality over time.
