中文：二苯并环辛炔-四聚乙二醇-马来酰亚胺英文：DBCO-PEG4-Maleimide，Mal-PEG4-DBCOCAS：1480516-75-3产品参数1 Catalog #: Y-PE-2144 Name: DBCO-PEG4-Maleimide CAS: 1480516-75-3 Formula: C36H42N4O9 MW: 674.8 Purity: 95% Availability: In Stock Ships within: 24 hours Storage condition: -20℃ Shipping: Ambient temperatureDBCO-PEG4-Maleimide is PEG linker containing a maleimide group and a DBCO moiety. The hydrophilic PEG spacer arm improves solubility in aqueous buffers. Maleimide group specifically and efficiently reacts with thiols to form stable thioether bonds. The low mass weight will add minimal spacer to modified molecules and will enable simple and efficient incorporation of DBCO moiety onto cysteine-containing peptides or other thiol-containing biomolecules. DBCO is commonly used for copper-free Click Chemistry reactions.
