Ovagen
Also written as Ovagen peptide.
A short bioregulator peptide from the Khavinson series, supplied lyophilised and typically in single-digit milligram quantities.

Ovagen is identified against a certified reference standard rather than against a published mass, because commercially supplied material varies in composition between suppliers. Purity is reported separately by reversed-phase chromatography at 214 nm and describes the chromatographable fraction only.
| Small quantities per vial mean the weighing error at receipt can exceed the analytical uncertainty of the determination itself. The vial contents are weighed and the figure printed. |
| Members of this series are close in mass and share residues, so identity rests on more than a nominal mass match. |
| No mass figure is published on this page. The composition supplied under this trivial name is not documented in a public chemical database, so identity is established against a certified reference standard at the time of analysis. |
Every compound fails in its own way. A generic peptide method applied without regard to these specifics produces a number that looks like a result and is not one.
Di, tri and tetrapeptides. Low molecular weight makes them the hardest class to quantify honestly: at this size the counter-ion and residual water can outweigh the peptide itself.
LC-MS identity, purity by RP-HPLC with a polar-retentive column since these peptides are barely retained on standard C18, and net peptide content because a purity figure alone is close to meaningless here.
Where the delivered milligram figure matters rather than the percentage, net peptide content by combustion analysis and water by Karl Fischer are added, and the certificate carries a closed mass balance instead of a single purity number.
| LC-MS identity | Measured mass |
| RP-HPLC purity | Area at 214 nm |

| Bacterial endotoxins | USP <85> |
What is the molecular weight of Ovagen?
No molecular weight is published for Ovagen on this page, because the composition of commercially supplied material varies between suppliers and an unverified figure on an analytical site is worse than an absent one. Identity is established against a certified reference standard at the time of analysis.
How is Ovagen tested for purity and identity?
LC-MS identity, purity by RP-HPLC with a polar-retentive column since these peptides are barely retained on standard C18, and net peptide content because a purity figure alone is close to meaningless here. Purity describes the chromatographable fraction only and is not the same quantity as the peptide mass delivered per vial.
What goes wrong when Ovagen is analysed?
Small quantities per vial mean the weighing error at receipt can exceed the analytical uncertainty of the determination itself. The vial contents are weighed and the figure printed.
What does Ovagen analysis cost at ANALYTON?
Peptide analysis, catalogue compound is priced at 341 US dollars, covering the determinations described on this page. Content, safety and elemental determinations are ordered alongside and are priced separately on the price list.
