Product Overview

Follistatin-344 is a synthetic research peptide corresponding to a naturally occurring glycoprotein involved in regulatory signalling pathways related to cellular growth, differentiation and tissue regulation. In laboratory environments, it is studied for its interaction with activin-binding mechanisms and its role in growth-regulatory pathway modelling. This lyophilized 1 mg preparation supports controlled in vitro research focused on peptide–protein interaction dynamics and signalling modulation studies.

Peptide Overview

Follistatin was first identified in the late 1980s during research into regulatory proteins involved in follicle-stimulating hormone modulation. The 344–amino-acid isoform has since been utilised in preclinical research settings to investigate growth-regulation pathways, protein-binding dynamics and signalling balance within complex biological systems.

Due to its clearly defined molecular structure and strong protein-binding affinity, Follistatin-344 is frequently employed as a reference compound in laboratory models examining regulatory feedback mechanisms and peptide-mediated pathway control.

Historical Background and Scientific Context

From the late twentieth century onward, research into growth-regulatory proteins expanded rapidly as laboratories explored signalling molecules capable of modulating cellular differentiation and tissue development. Follistatin-344 has played a significant role in this field, serving as a key research tool in studies investigating activin–myostatin signalling pathways and regulatory protein interactions under controlled experimental conditions.
