4-Arm PEG-amine (MW 5000) 是一种 PEG 连接子。反应性伯胺或 NH2 可与醛、酮快速反应形成亚胺。亚胺进一步还原后通过还原胺化形成二级胺。胺可与活性羧酸、NHS 酯反应形成稳定的酰胺键。4-Arm PEG-amine (MW 5000) 是有用的交联剂，可用于药物输送。
| 生物活性 |
4-Arm PEG-amine (MW 5000) is a PEG Linker. The reactive primary amine or NH2 rapidly react with aldehyde, ketone to form imine. Imine upon further reduction forms secondary amine via reductive amination. Amine reacts with activated carboxyl acid, NHS ester to form stable amide bonds. 4-Arm PEG reagents are useful crosslinking reagent and used for drug deliver. |
