Applications:
- Proteomics
- Peptide/Protein Analysis
- Peptide/Protein Purification
Features & Benefits:
- 2-D HPLC with a Single Column
- Ionic Interactions
- Reversed-Phase
- Separate peptides and proteins that differ only by a single amino acid
- Enhanced selectivity for closely related peptides and proteins.
- Increased peak capacity compared to reversed-phase and ion exchange.
- Increased LC-MS sensitivity using formic acid and ammonium acetate.
- Completely Scalable from capillary to prep
