Research Overview
Arenicin-1
Marine annelid peptide with strong preclinical antibacterial activity and a stable structural motif that is useful for peptide engineering.
FS315
Follistatin-315 is a key reference isoform in studies of muscle anabolism and reproductive/endocrine biology. In muscle research, it is relevant because it suppresses activin and can indirectly blunt myostatin pathway output.
