Follistatin in brief
Follistatin comes in one strength, 1mg x 10 vials, at $183.87 for the box of ten ($18.39 a vial, $18.387 per mg).
Nothing is held on the shelf: this is a special-order line, brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.
What Follistatin is
Follistatin is a recombinant glycoprotein, the 315-residue isoform in most preparations, produced in mammalian or insect cells and folded with its many disulfide bridges intact. It is a cysteine-rich, secreted protein, not a synthetic peptide, and its certificate is a protein certificate.
Its certificate reports purity and identity by the methods it names (size exclusion and SDS-PAGE for purity), endotoxin and the net content; the desk answers for an activity or binding figure on a particular batch. Stored frozen. The mass is not a single number because the glycans vary.
Follistatin beside IGF-1 LR3 and ACE-031
Its neighbours: IGF-1 LR3 at $20.464 per mg at 1mg (IG1), one chain of 83 residues whose mass can be calculated, 9,111.6, where Follistatin’s glycans leave it none; ACE-031 at $1.980 per mg at 1mg (AE1, in 50-box lots), a glycosylated Fc dimer of about 100 kDa, where Follistatin is one chain.

Buy Follistatin in bulk
Follistatin is sold in bulk by the sealed box of ten vials, and every account starts at list price. Two discounts can lower it, the size of one order (from $5,000 of goods) or the account’s tier (from lifetime paid spend), and the better one applies, never both. Priced below on FN1, 1mg x 10 vials.

Specification
The limits this compound is supplied to. Its purity limit is stated on each batch certificate rather than here, and the desk gives it for a batch before you order.
| Purity | On the batch certificate, with the method named there: size exclusion and SDS-PAGE for protein and glycoprotein lines, not an RP-HPLC area percentage |
|---|---|
| Identity | Against the reference standard by the method the batch certificate names |
| Endotoxin | Reported on the batch certificate |
| Net content | Label claim ± 5 % |
| Closure | 2 mL glass vial, bromobutyl stopper, aluminium flip-off seal |
| Storage | −20 °C, dark and dry; brief ambient transit tolerated |
| Shelf life | 24 months from manufacture; retest date on the batch record |

Questions about Follistatin
How does Follistatin differ from GDF-8 and ACE-031?
All three are recombinant proteins, specified by size exclusion and SDS-PAGE with an endotoxin line rather than by one RP-HPLC figure and a calculated mass, but they are built differently. Follistatin, cysteine-rich and N-glycosylated, is the 315-residue isoform in most preparations, and its glycans leave it no single mass to quote. GDF-8 is two 109-residue chains joined into a disulfide-linked dimer of about 25 kDa, and ACE-031 a receptor domain fused to an IgG1 Fc, a glycosylated dimer of about 100 kDa.
Which other lines come from mammalian cells, and what do they share with Follistatin?
Two other lines’ pages name mammalian cells: ACE-031, a glycosylated Fc dimer of about 100 kDa, and EPO, a 165-residue chain carrying four glycans, one of them O-linked. Follistatin, from mammalian or insect cells, is N-glycosylated too, and the three share what their glycans bring: no single calculated mass, and purity from SDS-PAGE and size exclusion, beside an endotoxin line. IGF-1 LR3 and IGF-DES, refolded from E. coli, each have one, 9,111.6 and 7,365.4.
How much does Follistatin cost?
It is sold only by special order, 50 boxes per strength, at $183.87 a sealed box of 10 vials, which works out at $18.387 per mg. The smallest order is 50 boxes of FN1, $9,193.50 of goods, with freight included to a US address. The price per vial is in this page’s price table.
What does Follistatin cost per mg?
It is offered in one size, FN1 at 1mg x 10 vials, which works out at $18.387 per mg at $183.87 a sealed box of 10 vials, sold by special order with a 50-box minimum. Freight included to US addresses from $1,000 of goods.
Can I buy a single vial of Follistatin?
No, and not a single box either. Follistatin is a special-order line, brought in on a 50-box minimum rather than held in stock, so the smallest order is 50 sealed boxes of one strength: for FN1, 1mg x 10 vials, that is 50 boxes at $183.87, $9,193.50 of goods. A box is sealed at fill with its batch number on it, and splitting one would break the link between the vials and their certificate.
Is Follistatin in stock today?
No. FN1 is special order: brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.
How is Follistatin stored?
At minus 20 degrees Celsius, dark and dry. Lyophilised powder tolerates a short spell at ambient temperature in transit, which is why boxes ship without ice. Storage and handling.
What is in a box of Follistatin?
Ten sealed vials of one strength, each labelled with the product code, the strength and the batch number; the trade also calls a box a 10-vial kit. Follistatin is supplied as a powder in a sealed glass vial and in no other presentation. Boxes are not split.
Is a certificate of analysis (COA) provided for Follistatin?
Yes. For Follistatin the batch certificate reports its purity and identity by the methods it names (size exclusion and SDS-PAGE for purity), endotoxin and its net content. The other lines on this page are the specification it is made to, and the desk answers for them on a particular batch. The certificate is sent with the shipment, and again on request, and any batch number can be verified on the certificate page.
Is this for human use?
No. Everything here is supplied for laboratory research only, to trade accounts, and is not for human or animal consumption. The research-use page sets out who can buy and what is not sold.
