Innolink Biotin 354S

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.

Following reconstitution, purge with inert gas, aliquot, and freeze (-20°C). Stock solutions are stable for up to 3 months at -20°C.
