NUCLEOSIL® 4000-7 PEI | |
Silica-based HPLC phase for anion exchange chromatography of proteins and peptides | |
Features |
Base material NUCLEOSIL® silica, particle size 7 µm, pore size 4000 Å Ion exchange capacity 0.15 mmol/g; protein binding capacity 61 mg BSA/g; Separation principle: reversible adsorption of negatively charged substances to positively charged groups on the exchanger material and their subsequent displacement by either increasing ionic strength or pH changes in the phase Eluent in column methanol |
| |
High selectivity for numerous proteins: e.g., β-lactoglobulins A and B, two proteins differing in just two amino acids, can be separated in only 10 minutes; biological activity of purified proteins is preserved Good binding and desorption kinetics for nucleotides as well For more applications click here. |
