Highly selective isolation using tags (His, GST, Flag) or specific ligands for maximum initial purity.
Separation based on surface charge using Cation (CM/SP) or Anion (DEAE/Q) exchange resins.
Size-Exclusion Chromatography for polishing and removing aggregates to ensure monodispersity.
Protein purification isolates a specific protein of interest from a complex biological mixture. NTSR specializes in multi-step purification strategies designed to achieve ultra-high purity while maintaining biological activity using state-of-the-art FPLC systems.
