中文：二苯并环辛炔-八聚乙二醇-琥珀酰亚胺酯英文：DBCO-PEG8-NHS ester产品参数1 Catalog #: Y-PE-2992 Name: DBCO-PEG8-NHS ester CAS: N/A Formula: C38H47N3O12 MW: 825.9 Purity: 95% Availability: In Stock Ships within: 24 hours Storage condition: -20℃ Shipping: Ambient temperatureDBCO-PEG8-NHS Ester is a click chemistry molecule cosisting of an NHS ester that is reactive specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. PEG8 spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions.
