FST Protein (C-human IgG1-Fc, Human)

1. Measured by its ability to bind human INHBA-his in a functional ELISA. 2. Measured by its ability to bind mouse INHBA-his in a functional ELISA. 3. Measured by its ability to neutralize Activin-mediated inhibition on MPC11 cell proliferation. The ED50 for this effect is typically 0.5-3 μg/mL in the presence of 10 ng/ml Recombinant Human ctivin A.

The secreted recombinant human FST/Fc is a disulfide-linked homodimer. The reduced monomer consists of 556 amino acids and has a predicted molecular mass of 61.7 kDa. As a result of glycosylation, rh FST/Fc monomer migrates as an approximately 70 kDa band in SDS-PAGE under reducing conditions.
