What differs between ACE-031 and Follistatin
Neither of these is a peptide and neither has an exact mass, so neither is specified like a peptide line. ACE-031 is a recombinant fusion glycoprotein: the extracellular domain of activin receptor type IIB joined to a human IgG1 Fc and assembled as a disulfide-linked homodimer of roughly 100 kDa. Follistatin is a secreted, cysteine-rich, N-glycosylated activin-binding glycoprotein, the long isoform arising from a 344-residue precursor. Glycosylation is heterogeneous by nature, so neither line has a single molecular weight to quote and both are identified and assayed on the batch certificate rather than against a figure on a sheet. Both tables carry an endotoxin line. On this list both are single 1 mg lines, so the comparison below is box price against box price rather than a per-milligram spread.

Questions
What is the difference between ACE-031 and Follistatin?

Which is cheaper per mg, ACE-031 or Follistatin?
At 1mg, the only strength both are offered in, ACE-031 is the cheaper per mg: $1.980 per mg against $18.387 (AE1 in 50-box lots, FN1 in 50-box lots).
Which comes in more strengths, ACE-031 or Follistatin?
Both are offered in one strength. Every strength is a separate line with its own code, price and stock state.
Are ACE-031 and Follistatin made to the same specification?
On the same methods, with no fixed purity figure on either sheet: both are protein lines, released on size exclusion and SDS-PAGE against the limit stated on each batch certificate, identified against the reference standard by the method each certificate names, with an endotoxin line, net content within 5 percent of label and a retest date on the batch record.
