Gentamicin C2a sulfate, EvoPure® is ≥95.0% pure Gentamicin C2a and can be used to study the Gentamicin biosynthetic pathway. Gentamicin C2a is a component of the Gentamicin C complex, along with Gentamicin C1 and Gentamicin C1a, and together this complex makes up 80% of the compound and has the highest antibacterial activity.  Gentamicin C2a and C2 are stereoisomers.  The higher antimicrobial activity of the complex is thought to arise from the lack of hydroxy groups on the 3’ and 4’ positions of the purpurosamine (2-amino-hexose) fragments.
