Polypeptide Hormone Follistatin 344 For Muscle Growth ( FST-344 )


General information:

Follistatin 344 is an activin-binding protein that aid muscle repair process and also improve motor functions. Follistatin 344 is made up of 323 amino acids.
Follistatin 344 binds directly with activin and acts as an activin antagonist. Follistatin 344 is a selective inhibitor of biosynthesis and secretion of pituitary follicle stimulating hormone (FSH). Follistatin 344 is a potent myostatin inhibitor and promotes muscle growth. Follistatin 344 significantly increase muscle growth and strength by blocking myostatin. Follistatin-344 is being preferred by athletes who are unable to exercise regularly or opt out from sports activities but needs massive muscle mass. Research studies demonstrated the anti-aging and tissue rejuvenation effects of follistatin 344. Follistatin is a glycoprotein encoded by the FST gene that is widely distributed in all tissues. A single follistatin gene encodes to various isoforms including FST317 and FST344.
These isoforms are made up of 317 and 344 amino acids that promote alternative splicing of mRNA. Molecular biological studies have identified potential linkage between polycystic ovarian syndrome and follistatin genes. Follistatin was first discovered as follicle stimulating hormone compound in the ovarian follicle fluid. The human Follistatin CDNA encodes for a 344 amino acid protein with 29 amino acids signaling the sequence. The domain that encodes for the EGF has kazallike motifs and a highly acidic C-terminal. The secreted Follistatin binds to TGF-family ligand as indicated and it regulates the activity of the signaling receptors. Previous studies had shown that the polypeptide is an antagonist to activin. Moreover apart from being an antagonist to activin, Follistatin inhibits activities of other TGF-beta ligand such as GDF-11, BMP-2,-4,-6 and myostatin among others. In most cases, Follistatin is expressed in the ovaries, pituitary gland, and endometrial cells in some cases.


Follistatin 344 Chemical Profile 

Name:Follistatin 344
Synonyms:FST, FS, Activin-binding protein.
Source:Escherichia Coli.
Physical Appearance:Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation:Lyophilized from a concentrated (1mg/ml) solution containing no additives.
Solubility:It is recommended to reconstitute the lyophilized Follistatin in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
