Highlights:

• Used in coupling of hydroxyl, amino or thiol groups to 6B-CL via a 12-carbon hydrophilic spacer arm.
• Pre-activated medium for immobilization of ligands containing amino (primary or secondary), hydroxyl or thiol group.
• Ideal for immobilization of alkali-resistant small ligands such as peptides, amino acids and carbohydrates.
• Epoxy-activated 4B-CL is a pre-activated medium for coupling sugars and other carbohydrates via an ether linkage to a hydroxyl group.
• Medium has a long hydrophilic 12 atom spacer arm which makes it particularly suitable for immobilization of small molecules.
