Highly sensitive real-time PCR method to identify species origin in heparinoids.

Heparinoids are the starting material for sulodexide production, a drug used as intravenous anti-coagulant, as an alternative to heparin. The origin determination in the starting material for sulodexide, heparin, and derivatives is crucial for safety (including the impact related to bovine spongiform encephalopathy) and efficacy of the final products. Therefore, European countries have decided to approve the production of heparin only from porcine intestinal mucosa.

High-throughput liquid chromatography/mass spectrometry method for the determination of the chromatographic hydrophobicity index.

A fast gradient reversed-phase liquid chromatography (LC) method, using an acetonitrile gradient was developed to determine the chromatographic hydrophobicity index (CHI), as reported by Valco et al. (Anal. Chem.
