Recombinant Human FSTL1 protein (NP_009016.1) is produced in Sia-Adjusted Human Cell Line. This expression system is used for the production of glycoproteins and antibodies with different sialylation degrees.
This gene encodes a protein with similarity to follistatin, an activin-binding protein. It contains an FS module, a follistatin-like sequence containing 10 conserved cysteine residues.
