KEY FEATURES:
• Polyethylene glycol (PEG) groups in spacer arm enhances water solubility of biotinylated molecules
• Spacer arms providing slightly different options for controlling steric hindrance and hydrophilicity
• Water-soluble; can be used under physiologic conditions
APPLICATIONS:
• Biotinylation: Label molecules and surfaces for assays or affinity purification methods involving avidin or streptavidin probes and resins
• Amine-activated: Primary amine can be crosslinked to proteins and material surfaces using EDC and other crosslinkers
