What MGF is
MGF, mechano growth factor, is the synthetic 24-residue peptide corresponding to the E domain, the C-terminal extension unique to the IGF-1Ec splice variant. It is a strongly basic chain rich in lysine and arginine with several asparagines and glutamines, and it is made on resin, not expressed, so its certificate is a peptide certificate.
The deamidation sites are what age; there is no methionine or tryptophan. It is very hydrophilic and takes multiple charges in electrospray. Compare with PEG MGF, which is the same chain carrying a polyethylene-glycol group.
MGF beside PEG MGF and IGF-1 LR3
Its neighbours: PEG MGF at $6.233 per mg at 2mg (PMF2, in 50-box lots), set side by side in PEG MGF vs MGF, its own 24 residues with polyethylene glycol conjugated, so its mass is a spread, not one figure; IGF-1 LR3 at $20.464 per mg at 1mg (IG1), 9,111.6 g/mol, the 83-residue IGF-1 analogue, refolded around three disulfides where MGF has no cysteine.
Reading an MGF certificate of analysis (COA)
Identity by mass. Average mass 2868.2 (C121H199N41O40). In electrospray the protonated ions come near m/z 2869.2 (singly charged), m/z 1435.1 (doubly charged), m/z 957.1 (3x charged); on our certificates the measured mass is matched to the calculated average mass, within about one unit.
- Oxidation: no methionine, tryptophan or cysteine in the chain, so oxidised forms are not the impurity to expect.
- Deamidation: 2 asparagines and 2 glutamines. The deamidated form is 0.984 heavier and a little more negatively charged, inside the tolerance of the average-mass line; telling it apart takes a high-resolution mass, which the certificate does not carry.
- Charge: near neutral pH about +5, basic, with 7 basic residues, so it takes multiple charges in electrospray.

Questions about MGF
Is mechano growth factor the same as MGF?
Yes. Mechano growth factor and MGF are names for the same thing. MGF is short for mechano growth factor, the 24-residue E-domain peptide of the IGF-1Ec splice variant. The certificate and the vial label carry MGF, which is the name the batch is released under.
What does MGF have to do with IGF-1 LR3?
They come from the same gene and are made in different ways. MGF is the E domain, the C-terminal extension unique to the IGF-1Ec splice variant: 24 residues, made on resin, with no cysteine and so no bridge to form, at 2,868.2. IGF-1 LR3 is the whole 70-residue hormone, lengthened by 13 residues at the N-terminus and with arginine at position 3, expressed in E. coli and refolded around three disulfides, at 9,111.6, so MGF weighs under a third of it.
How much does MGF cost?
It is sold only by special order, 50 boxes per strength, at $60.25 a sealed box of 10 vials, which works out at $3.013 per mg. The smallest order is 50 boxes of FM2, $3,012.50 of goods, with freight included to a US address. The price per vial is in this page’s price table.
What does MGF cost per mg?
It is offered in one size, FM2 at 2mg x 10 vials, which works out at $3.013 per mg at $60.25 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 MGF?
No, and not a single box either. MGF 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 FM2, 2mg x 10 vials, that is 50 boxes at $60.25, $3,012.50 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 MGF in stock today?
No. FM2 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 MGF 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 MGF?
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. MGF 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 MGF?
Yes. For MGF the batch certificate reports its purity, net content and identity by mass spectrometry. 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.
