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.

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
