Chromatography media are crosslinked agarose and dextran beads functionalized with various functional groups for affinity purification of biomolecules (protein, antibody, enzyme, polypeptide, DNA, etc.). They feature high degree of functionalization. The listed products have average bead size of 90 ┬Ám and crosslinking degree of 4%. Other types of chromatography media are also availble. All listed prices are based on per package and in USD.

Carboxylate functionalized agarose carry negative charge in buffer with pH greater than 4. This medium can reversibly bind to cationic compounds through ion exchange. They can also permanently bind to the primary amine groups of biomolecules after activated to NHS version through an easy procedure. This binding is more efficient than those based on aldehide or cyanogen bromide (CNBr). NHS activated version are also available with similar price, but they are not stable during storage.We suggest that customer do fresh NHS activation right before use.
