2-8°C
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.
