Reactivegroup: OPSS,NH2. Reactiveto: NHS. Description: OPSS-PEG-NH2 is one of heterobifunctional polyethylene glycol crosslinkers that have a thiolreactive group and a primary amine group bridged by a linear PEG chain.OPSS is a commonly used sulfhydryl reactivegroup that reacts readily with free thiol groups at pH 4.5~8.5 to form acleavable disulfide bond. Meanwhile, primary amine can be used to react with manyamine reactive groups such as NHS, COOH, etc. PEG linker between OPSS and NHSoffers better water solubility, less steric hindrance and enhanced reactivity. Comparedto other crosslinkers, PEG crosslinkers from have more choices fortheir functionality and are easy to use; all crosslinking reactions can becarried out in aqueous solution without need adding any organic solvents. Handlingand Use: OPSS-PEG-NH2 is sensitive to light and temperature. Forbest use, material should always be kept in low temperature in dry condition. Avoid frequent thaw and freezing. For moreinformation about using this product, StorageConditions： OPSS-PEG-NH2 should bestored at -20℃.Desiccate. Protect from light. Materials may be handled under inert gas forbest stability.
