Follistatin-344 impurity profile
Every named species the index has reported alongside Follistatin-344, how often, at what level, and what its presence implies about the synthesis or the handling. Purity is not a defined quantity for this substance, so the impurity table describes what eluted rather than what is impure.
| Named species | ΔRT (min) | Δ mass (Da) | Seen in | Median % area | Max % area |

Degradation pathways
Degradants are a handling finding rather than a synthesis finding. A lot that shipped clean and arrived oxidised tells you about the courier, not the chemist.
- aggregation
- proteolytic clipping during expression and purification
- glycosylation heterogeneity where expressed in a eukaryotic system
