Description

A modified biotin conjugate in which biotin is linked to a bis-aryl hydrazone chromophore and aromatic succinimidyl ester via a long-chain PEG4 linker. The bis-aryl hydrazone chromophore allows for direct spectrophotometric quantitation of total incorporated biotin. The long-chain PEG4 linker preserves biotin/avidin affinity as well as increases solubility. The aromatic succinimidyl ester allows for higher efficiency modification of amines in aqueous buffers.
