What is Fragment 176-191?

Fragment 176-191 is a synthetic 16-amino-acid peptide with the sequence Phe-Leu-Arg-Ile-Val-Gln-Cys-Arg-Ser-Val-Glu-Gly-Ser-Cys-Gly-Phe. The name comes from where it sits in the parent sequence, residues 176 through 191. It has the formula C78H123N23O22S2 and weighs 1,799.1 g/mol.

A disulfide bond joins the cysteines at positions 182 and 189, which pulls it into a loop. It’s almost the same as AOD9604, which has a tyrosine where this peptide has phenylalanine. That’s one oxygen atom of difference, so only mass spectrometry, not HPLC, will tell you which one you have.

What researchers study Fragment 176-191 for

Fragment 176-191 is studied mainly in fat metabolism models in animals. It’s the parent sequence for AOD9604. For laboratory research only. Identifiers are on NIH PubChem.

How to store Fragment 176-191

Keep it in the fridge at 36 to 46 °F (2 to 8 °C) and away from light. Keep it cold after reconstitution.

Most labs reconstitute with Research Water, which is sterile-filtered water with 0.9% benzyl alcohol.

When it’s time to reconstitute, let the vial come to room temperature first. Add the solvent slowly down the inside wall of the vial so it doesn’t hit the powder directly, then swirl gently until the liquid is clear. Don’t shake it. Write the date on the label so you know how long it’s been mixed.

Fragment 176-191 FAQ

Why is it called Fragment 176-191?

It matches residues 176 through 191 of a longer parent sequence.

Is Fragment 176-191 the same as AOD9604?

Close, not the same. AOD9604 swaps the first phenylalanine for tyrosine.

Is Fragment 176-191 5mg for human use?

No. It’s sold for laboratory research only. It isn’t approved for human or veterinary use, and we don’t give dosing advice.
