应用
- Putrescine in food analysis: A study demonstrated a novel method for the selective extraction of dietary polyamines, including putrescine, from chicken breast, utilizing lab-on-a-chip electromembrane and dispersive liquid-liquid microextraction techniques for enhanced food analysis (Barzegar et al., 2024).
- Putrescine in biochemical analysis: The application of Electrostatic Repulsion Hydrophilic Interaction Liquid Chromatography (ERLIC) for the quantitative analysis of polyamines such as putrescine showcases its importance in biochemical assays, providing precise measurement tools for research and development (Dörfel et al., 2024).
