Decapeptide-12 runs on the lab’s peptide purity and quantity method: reversed-phase HPLC on a C18 column with a water and acetonitrile gradient containing 0.1% TFA, and UV detection at 214 to 220 nm. Purity is the main peak’s share of the total peak area, quantity is measured against a reference standard, and identity is confirmed by retention time and UV spectrum against the same standard. LC-MS confirmation of the mass is quoted separately.
In finished creams and serums the peptide is present at low levels and the formula affects extraction, so finished-product assays are quoted; see topicals and cosmetics testing.
Send 1 vial or 50 mg of raw powder per sample; for a solution, tell us the claimed concentration. Results arrive in 3 to 5 business days.
Deletion sequences from synthesis that are missing one residue, and oxidized tryptophan. Both usually appear as separate peaks in the purity result.
Yes, as a quoted assay. The peptide is extracted from the formula and measured by HPLC, with the result reported as % w/w or ppm against the label.
