What is Follistatin 344?
A naturally occurring protein of 344 amino acids first identified in ovarian fluid, Follistatin is studied as a regulator of muscle and reproductive biology. Research focuses on its ability to bind and neutralise growth-regulating proteins such as myostatin and activin.
- Studied for promoting muscle growth by blocking the body's muscle-limiting signals.
- Researched for its effects on increasing muscle mass and strength.
- Examined for its role in fertility and reproductive biology.
- Studied for supporting tissue growth and repair.
For research use only. Not intended for human use.
As an endogenous glycoprotein antagonist of activin and other TGF-beta superfamily members, Follistatin has occupied a unique regulatory position in ligand-receptor signalling research. Follistatin 344, also designated FST344, is a 344-amino acid recombinant glycoprotein with an approximate molecular weight of 37,000 g/mol. Produced as a recombinant protein.
In vitro co-immunoprecipitation and crosslinking studies have characterised the stoichiometry and structural determinants of the FST344-activin A complex. In vivo rodent models have compared the biodistribution and ligand-trapping kinetics of recombinant Follistatin 344 against shorter FST288 and FST303 isoforms.
Manufactured in a cGMP compliant laboratory to a guaranteed purity of 98% or above. Every batch undergoes independent testing using HPLC and MS-UPLC analysis before dispatch. Vials are vacuum sealed and stored in a temperature controlled, monitored cold storage system. Certificates of Analysis are available on request.
Sold strictly for in vitro research purposes only. Not for human consumption. Intended for use by qualified researchers in laboratory settings only.
