5mg of PP-FLGR-242 (5mg)

Follistatin (FLGR242), is a novel fragmented, modified version of Follistatin-344 (FST-344) that does not bind to the protein activin. Activin is responsible for the negative effects of myostatin inhibition such as unwanted cellular growth in laboratory models. It also contains a patented albumin binder.

Follistatin protein (FST) fused with an albumin-binding construct that uses a hydrophilic glycine-serine linker to achieve high-affinity binding to serum albumin (<20 nM Kd). This recombinant technology allows researchers to study follistatin-albumin interactions and protein trafficking in experimental systems.

Research applications include muscle mass development studies, activin neutralization assays, and TGF-β superfamily pathway modulation with albumin binding dynamics. The construct maintains biological activity while enabling investigation of albumin as a carrier protein.

US GMP-manufactured with third-party verification and comprehensive COAs for reproducible research outcomes.
