Cosmosil® Protein-R
Nacalai Tesque COSMOSIL Protein-R Semi-preparative HPLC Guard Column, 5µm, 300Å, 20mm I.D. x 20mm Length, 1/Pk
Product Number: 08692-81
Wide Pore HPLC Column for Protein Chemistry
COSMOSIL Protein-R is a reversed phase HPLC column designed specifically for protein and peptide separation. COSMOSIL Protein-R provides significantly improved peak shapes, high recovery rate and outstanding stability at low pH, which are often problematic for the separation of proteins and peptides with conventional C18-300Å and C4-300Å columns.
- Excellent separation
- High recovery rate
- Outstanding stability at low pH
