Innolink™ Biotin 354S NHS-Chromogenic Biotin 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. 产品信息 Form Solid Molar mass 810.9 Protect from Moisture 是的 Purity ≥90% by NMR Solubility DMF Chemical formula C38H50N8O10S 商店和运输信息 Storage +2°C to +8°C Ship Blue Ice Only Standard Handling
